After what seems like forever gathering parts I finally started putting it all together. Should be ready for calipers tommorrow. Click the WKDTITE link below and check out page 3. I'll update it again later with completed pics.

love to see it, but link had other thoughts. hopefully after a profitable adventure in alaska this summer I'll embark on a similar swap

I've got C5 brackets available if anyone is interested in the swap.

Looks good on the progress Dennis graemlins/thumbsup.gif

Hey Joe, I came up with a solution to your wheel stud problem. A GOOD hardware store will have socket cap screws in lengths from 1"-2" threaded all the way up. Tap the hub and use the screws-they have be 1/2X20 though, hole in hub for stud is too big to tap for 7/16. :D

Huh. I was just looking at Auozone's online catalog to see what rotors use the same bearings ads the B-body and 1LE stuff that is commonly used on the tall-spindle swap (A3 and A6). I noted that the '82-up Camaros used the same inner and a different out (or vice cersa - I forget), but obviously they still fit the spindle, since you're using a '90 rotor as a hub. Good to know.
<goes and looks at AZ website again>
Ah! I see. I didn't look far enough. All 82-89, and V6 (RS) 90-92 use the A6 inner and A34 outer, but 90-92 Z28/IROCs use the A6 inner/A3 outer. Interesting. Looks like '93 is where they went to the sealed bearings?
Is there any particular reason that you used a '90 rotor instead of the '80 rotor that would have come with thte spindle? Is the '90 lighter, or thinner, or better offset or something?

On the wheel studs, couldn't you have used the same studs that Global West says to use with the B-body/1LE rotors? I believe it requires drilling the holes slightly.
<checks references>
Yup - have to be opened up top 35/64" (14mm). 'Course, GW doesn't say what studs to use, I'm ASSuming stock A-body application.
Though, I DO like the cap screws... certainly easy to replace!

Dennis & Kevin,
I've found a way around to use 7/16" studs, but haven't found the time to post it on my website (that seems to be the common theme these days).

But yes, it does involve 14mm drill bit and ARP studs. Not what I was after to allow the "user" to find things at the parts counter, but it works and you have some very nice wheel studs.

Kevin,
Sorry for not answering this in my other post.

When I initially got into this swap I tried to use the B-body rotor as a hub. As you've found out, the offset between the B-body rotor and F-body rotor was about a .250" difference. See my website for the details.

I had to find something better. So off to the junkyard I went to find something and came across the F-body hub on the B-body spindle by just fooling around, measuring & swapping parts.

The F-body hub tucks in the brake setup better which aided in the C5 bracket design. It will also place the wheel mounting position pretty darn close to where a stock tall spindle will place your wheel.

Joe

Yeah, I looked into drilling out the hubs and using different studs but that meant ordering parts, with the cap screws I can just pick them up downtown and if I break one or strip it(eeekkk) it is easy to find a replacement. I used 90 instead of 80 because of the "Joe" measurement. You'll have to read 72ssabody's page to know what that means. It refers to how far the hub places the rotor away from the spindle.

Ah, I see. I have 72SSAbody's website bookmarked, and I think I even printed out the brake pages to put in my reference binder (I don't trust the permenace of the web, or me being able to find the site later...) Obviously, I didn't read it closely enough smile.gif
So the earlier F-body discs (or the V6 discs) with the A34 outer bearings will also work, I see. Same spindle diameter, then. Goody, that makes availability skyrocket! I'm going with the 1LE rotor, single-piston caliper for now, but I intend to push on to the C5 stuff later.
BTW, excellent website 72SSAbody. I think I printed off most of it for future reference... :D

Er, "Joe" measurement? I understand the concept of the measurement itself, but from whence does the name come? Is that 72SSAbody's real name?

Yeah, 72ss is Joe.

You guys could save yourself a whole lot of hassle with a set of the super cool hubs and brackets shown here:

Shameless plug.

Those are very nice, but I've got gobs more time than money, and access to a mill and lathe... smile.gif

How much are those, anyway? Just incase I win the lottery or something tongue.gif

They are cheap!!

$80 for the brackets
$175 for the Hubs bare

Gary King

so the hub and bracket bolt on to stock b-body spindles?

what other parts are required (different studs, bearings, etc)?

Do you have any estimates on what the swap would end up costing, assuming you bought all new parts?
