Re: My '66 SS L78 rebuild

Yikes, I feel your pain. I stepped on a pile of hot ash several years ago, while on vacation. The bottom of my foot was one huge blister. That sucked!

As for your front springs, enlist the family or a few friends to sit on your frame. I put a couple of 2x4’s across the front frame horns and had my son and daughter sit on it, while stood on the cross member, whenI removed my upper control arms a few weeks ago. Worked like a charm.

Got the upper control arms on, BJs trying to get the lower control arms into the frame... not going, tried a jack with a block of wood but frame stared lifting off the jack stands

I got the new axle bearings and seals, and rear brake assemblies installed. Need to figure what lube for bearings seals and splines on the new shafts...

Maybe this evening I’ll get the rearend in position... maybe...

New steering box has some light surface rust. Debating if I should clear it, or paint (Eastwood’s Diamond Clear - satin) with “cast iron” paint...

Well, more progress

I lubed the new seals and axle bearings, installed my Moser axles, added some Tom’s C-clips and his cross-shaft... added gear oil, GM limited slip additive, and a new cover and gasket...

I then rolled it over into position, installed the control arms and frame reinforcements. All mounting bolts are only finger tight. Since 6 of the 8 mounting positions used spherical bearings, I guess I can torque those now, as the will pivot internally.

Running Global West tubular lower arms (TCA4?) with spherical joints at the front frame positions and poly (?) at the rear end. Upper arms are Edelbrock adjustable arms with spherical bearings at the front (able to adjust pinion angle on the car), Edelbrock tubular frame reinforcements and Currie Johnny Joints in the upper housing ears.

Springs are Edelbrock/Eibach and the shocks are Edelbrock IAS. Springs and shocks are new in box, but 13-15 years old.

I have a “repro” rear sway bar that I will mount to the lower control arms ( yes, I know this isn’t the most effective design). The Global West arms have the holes for the “stock” rear bar.


Front will have a 1.25” bar and the Edelbrock / Eibach springs and shocks... but otherwise stock rebuild.

Quick ratio manual steering... I might have to switch back to the stock ratio and I am already considering adding power steering and plan to gather the correct parts... but I am getting ahead of myself...

Whew...

Anyway, it’s great to see progress.

Difficult tasks coming up; getting the lower front control arms into the frame pockets ( struggled with that today)., installing front springs ( need spring compressor ), install rear shocks ( need Macpherson Strut spring compressor?)... hoping that’s the only tough stuff coming up

Looks great, Tony. I made my own spring compressor with all-thread rod that goes through the shock mount hole on top, and a Snap-on retainer on the coil. A tool similar to the fork could be borrowed from auto parts store.

Re: My '66 SS L78 rebuild

Stock rear springs are really soft, not sure you'll need any special tools to attach the shocks. Or maybe you said somewhere along the way that you're using some special shocks?

is that the Corvair front cross-member?

The local stores have free rentals...

Running Edelbrock/Eibach springs; shorter, but stiffer than stock... I may try to get those installed in the next few days, but I realize last night that I still need to clean and coat the spring retainer plates...



I built my body cart so that I had nice lateral bracing and just enough clearance over the tires, but when I removed the rear shocks, the rear rose enough that it caused some interference issues... Nothing major, just an inconvenience...

Yes, that is the Corvair's front subframe in a fixture for mockup and measurements. I already had the all-thread in use to support the lower control arm, so I included the fork for the photo. Here is another photo to see the caster/camber measurements being made. The Corvair is being modified with Chevelle ball joints, spindles, and C5 brakes. Homemade tubular upper A-arms are the works too. There is more information on the V8 Vairs Facebook group if interested.

Re: My '66 SS L78 rebuild

Well, with the help of my neighbor, I got the rear shocks installed. I needed to sit on the rear of the frame and bounce a little to allow the lower shock eye to slide onto the stud...

But now the springs and shocks are installed in the rear, I tightened all the upper control arm bolts, snugged the lower arms at the rearend (I'll torque to spec when its all back together on and on the ground... Still need to tighten the front mount bolts for the lower rear control arm...

I also got the front lower arms in place, but the bolts are still loose...


Today I drilled out the mount holes on the steering arms, as stock used 7/16" and the new setup uses 1/2 bolts... Tomorrow I will clean the steering arms, spindles, idler arm, steering box and tie rods, and give them some "cast iron gray" paint... The new Proforged tie-rods are already coated in black, so I am still debating leaving them black, or the gray... The adjuster sleeves are black (billet aluminum- Edelbrock?)...

My goal is to have it "rolling" by the end of the weekend... maybe... On the rear, I still need to grease the backing plates at the shoe pads (I forgot), and paint the new drums to protect from rust... Then I can bolt on the rear wheels...


DOH! Just my luck... I was working on the upper rear control arms, and so I put the jack under the rearend (toward the pinion yoke). I used some cardboard to protect the finish... After i was done, I noticed a grease spot on the cardboard, and another on the concrete... Right below the pinion seal!


Rear end has about 2000 miles on it (rebuilt around 1993), but hasn't been driven since about 2005... I guess the 15 years of sitting dried out the seal... 2 steps forward, one step back... Now I have to find my pinion yoke holder (3/4" iron pipe I drilled two holes and used longer Grade 8 bolts to hold the pinion. I thought it was this rearend, but it was another 12-bolt in my other Chevelle that I broke the pinion yoke and had to replace it...

Re: My '66 SS L78 rebuild

Clean prepped and painted my steering arms, steering box and spindles...

I still need to decide if I want to paint the tie-rods "cast iron" and match the centerlink, pitman and idler arms, or leave them black... Adjuster sleeve is black anodized aluminum, so not planning on painting that...

Today I will clear the centerlink, and give the new drums a coat of paint, just to keep rust away...


I also plan on installing the springs and spindles... We'll see how that goes...
