8-14-2020 Update

Have not posted much related to the Camaro lately.  2021 is dedicated to the suspension (including 12-bolt).  The supplies are starting to trickle in:

engine mounts and misc screws for the misc parts in pic #2 New cross shaft for the 12-bolt rebuild – American Express had a deal with Summit Racing where if you spend $50 you get $10 back.  I couldn’t pass up:

5-28-2017 – 12-bolt

Not too much to report.  Did some cleaning and scuffing inside the shell and around the patching I did yesterday for the 4-speed trans hump.  There were a couple of spots inside the shell I want to go over again with some more epoxy.

I also pulled out the 12-bolt to clean it for the first time since having it blasted and epoxied.  Glad I did because I discovered a couple of spots I want to re-do in epoxy before paining it:

Sprayed the inside with brake cleaner

There is also another spot like this on the other side.

12-bolt Sand Blasted & Primed

The 12-bolt has been sand blasted & has been Epoxy primered… This was done by someone else (the friend I bought the engine from knows someone who did this for me) – I will paint this Spring once it is warm enough. Tried to find a before picture:
and after – it looks even better in person!
I will need to clean the inside again before rebuilding it.

Started the dis-assembly of the 12-bolt for inspection.  First had to get the drum brakes off with a big hammer:


I had to get the drums off (will be replacing brakes with disc) so I can get the spindle out which is a part of the bolts that hold the wheel on.IMG_0948

Once the spindle is out, I think the 4 bolts (2 shown in red) will be all I need to remove to get the rest of the brakes off the axle.IMG_0949 IMG_0950

This is my setup for working on the read axle.  Got the cover off without breaking any bolts (sprayed with Kroil for a couple days prior).  I can still wheel it around the garage with this setup.  Will let it drain over night before doing much more.  I have a DVD to refer to for the rest of it.  I need to inspect the portion that holds the posi in place.  If they are in bad shape, I won’t be able to use the axle as they are matched to the rear axle.  So I will need to do some inspection before determining if I can use this and before ordering replacement parts.  I do know I will be changing the gearing to 3:73 gears.IMG_0951

Got to use my magnetic bowl – those are great for holding bolts and not losing them if you kick the dish!IMG_0952
