Ok, after much anticipation, my '68 is on the road, and aligned. Here's the scoop:

1. PST Polygraphite kit with the following changes; b-body ball joints, g-body outer tie rod ends, f-body 1.25 swaybar bushings, offset inner arms (installed reverse of normal).
2. Stock coil springs (new)all around, ordered from Ground Up.
3. New KYB shocks all around.
4. 12" b-body spindles from a '84 Caprice Wagon.

I had it professionally aligned on Thursday by my local shop that sets me and the local Porsche club up for SCCA racing. They were very happy with the job BC and I did. The big question was the amount of shims that would be needed without using GW upper arms. Here's what I got with a general "street" alignment, not a Pro-Touring type with lots of negative camber:

Camber Right .5 deg
Camber Left .5 deg
Caster Right .4 deg
Caster Left .8 deg
Toe Right .10"
Toe Left .10"

If I measure the shim pack, the back of both sides is just less than 3/4", and the fronts both have just less than 1/2". That beats the Global West claim of "will require over 1-1/4 inches of shims (if your lucky) with probable steering column or exhaust interference." Well, I guess I beat that.
Now, this is on a car with a good frame, so it is possible that you could have problems. Interestingly enough, my alignment guy told me if we hadn't used the offset arms, we would've used even less shims, but he was very happy that with the extra room, there was extra adjustment for later if I want to dial the front end in differently. He is also convinced that in about 6 months he'll be able to take out a few shims once the front gets settled to the new parts.

At any rate, there you have it; I didn't use the GW arms, and it worked. BTW, I'm not anti-GW, their parts are beautiful, but I am on a budget, and couldn't afford them.

If you have any additional questions, please contact me. My website also has all of the parts listed that were used, so check there for those if you are interested.

Dave that's great information. I've seen it done before but never did it myself. No need to 'cause I have the hard to find original caliper brackets. Can't see forking over the $200.00 places want for those.
Now you gone and proved that money can be saved on the expensive upper arms.
Heard from Bill (BC) that he is going to go to the 8" dual diaphragm booster. I and others have said that this can be done, with a little extra work, without shelling out the $350+ for those custom boosters.

[Gandalf80]

SWEET! I am going to do that for sure!

So are you saying that you could have done the swap to the b-body spindles without even changing to the offset arm?

Do you have headers? If so how much clearance do you have with the offset bar?

What was the total cost for this swap minus the sway bars?

thanks!

After talking with Bill and drawing it out on paper, we still think the offset arms reversed is the best way to go.

As for the cost, hmm. I spent about $1200 for the suspension and brakes together I think. I'll break out the cost of everything and post it later tonight. If I had to guess, I'd say $500 for the brakes in total.

I'm running stock exhaust manifolds. I have tons of room left. I'm also running a small block, but don't think it would be an issue, unless it's a big block. I'll see about measuring that tonight too.

Thanks, i'm running a 454 with 1 7/8 tube headers right now, and I don't know how much clearance I have.

Do you have any idea how much closer the offset shaft is to the headers than the stock shaft was?

Think I'll jump in here,

Chris,
the problem with headers should not be the iner shafts, but possibly the ends on the upper control arms where the end links nount to. Overall, I'd say you are bringing the upper control arm in approx. 1" from where is was before. Using the offset inner shaft, you are actually putting the offset towards the wheel, not away as would be in the 'normal' use of the offsets. This means that the inner shaft is actually further away from the headers or anything than the ends. The closest thing to being in the way is the steering shaft, maybe David could measure the distance from the offset shaft to the steering shaft.

Gandolf,
In case you didn't know, David redid his rear suspension at the same time, so I think alot of the $1200 was the new rear lower control arms, rear sway bar, KYBs, etc. Outside of a few minor cost adjustments from wrong parts, etc., I think he did real well when you look at the GW page and realize the same thing in a kit with USED spindles runs over $1,800!!

Hope that helps,
Bill C.

I just completed the same swap but using Hotchkis upper control arms. Everything else for the swap is the same so you should be able to back the cost of the tubular a-arms or other parts you dont need. I was going to go without the tubular a-arms but figured my luck it wouldnt work and I would have to do it over again. Since this is my daily driver I couldnt afford the time if I messed it up.
Hope this helps.

p.s. I fully believe the conversion can be done without special arms. Height of the car (lowering helps) and differences in frame sag will vairy the results. I decided I would upgrade for the full performance benefits while I was doing the labor cuz it would only be an additional couple hundered dollars more to upgrade (if you back out the cost of the new poly bushings, upper balljoints and offset shafts) you would need to buy anyways.

David, I have two questions for you.
First, you said you used B-body ball joints, did you have to have them machined at all? Everything I've read about the swap says they need .080 machined off them, it would be much easier if they didn't. Secondly, I noticed on your webpage you said you are using a manual master cylinder. Does this affect brake performance at all, it seems I never hear about discs without power assist but that is exactly what I want.
I thinks I am definately going to do this swap, I was already planning to rebuild my suspension, and the front clip is off making it easy to access. Thanks,

Rob

Update...

Chris, as for the measurments, Bill is right, it really depends on the end of the arm, not the bolts. I have 1" between the arm and my exhaust manifold on the back, and 2" clearance in the front of the arm. The steering arm is close, but not even close to touching. It looks to be about 1/2" of clearance with that. Hope that helps.

Chuck, glad to hear you got yours on and working, I know mine being a daily also, thats a big concern!

Rob, I went manual disc, since I had manual drums. Honestly, it would have been easier to do the power ones, but that said, it works great! The master cylinder I used is Non-power Disk from 1975-1980 Camaro Car Quest #BPR 20-1751. I did have to get an even shorter rod than my car originally had. I don't know the part off that, it came out of a box we pilfered in Bill's garage. So, that might be a hit and miss. The other option would be to adjust the rod. As far as turning the bottom ball joint, it wasn't necessary on mine. My machine shop did it though when the pressed the bushings in for me.

Ok, cost:

Master Cylinder 24.00
Brake hoses (2) 83.00
1LE Rotors (2) 145.00
Wheel studs (10)14.52
Banjo bolts (2) 8.00
Brake spindles, calipers (cores), prop valve, etc. 50.00
Calipers (preloaded) (2) 80.00
Labor to press new studs 30.00

Brake total 434.52

A6 Bearings (2) 12
A3 Bearings (2) 17.35
Outer Tie Rods (2) 47.46
PST Super Poly front end kit 359
Springs (4) 140
KYB Shocks 100
Rear sway bar/control arm kit 275
Suspension total 950.81

Grand Total 1385.33

I chewed up some money on the rear sway bar setup with the control arms, but since I couldn't find any nice ones locally, I just bought them anyway. The brakes were actually pretty cheap overall. The extra tie rod ends are due to my mis-ordering them from PST. So, I'll see about sending those units back.

Overall it is a great conversion! The car handles great, and brakes even better. I am trying to get used to throwing a car this size around. It handles like a new car.

"Banjo bolts (2) 8.00"
Oh, you Colorado guys are rich. Next time you are boneyard picking, check out the Chrysler mini-vans. Rows of that fine equipment down here. They use the same diameter and length as Chevy but have a 9/16 hex head on them. On a bad day they are 4 for a dollar. LOL
John

[BC]

Yeah John, that is ridiculous, but Dave's rich! LOL!

Thanks for the tip on the bone yard stuff, but is that the same for a stock Chevelle, or for later cars?? One thing I found out is that it looks like GM changed the size of the banjo bolts sometime in the 70's, even tho they are the same threads. The later ones have a smaller (7/16 I think) head on them and the taper is a little different. Also, the fitting on the brake line are thicker, so the banjos are a touch longer.

Maybe I'll pull one just to play next time I'm at the junk yard...

Bill C.

[Gandalf80]

Haha i'll take the 2 minute drive to the chevy dealership and pay the $4 rather than making the 20 minute trip to the scrap yard and 15-20 minutes of finding removing a bolt just so I can get an old rusted bolt for 50 cents

If I needed 10-15 of them then that would be a different story

Chris
It was part joke to Bill and Dave and part information. Yeah Bill, they will fit a "72" caliper.
The Chevy dealer parts area here is not open on Sunday. A lot of times my local pick-a-part is the only place I can do my Sunday shopping. Rust on banjo bolts?? This is Southern Cailfornia.

Stoopid question time...What is an offset shaft?
