VooDoo 10-bolt Rear End Rebuild

I wanted to do something to beef up the stock rear 10-bolt IRS.  I still couldn't afford a Tom's 12-bolt IRS so I went with the next best thing.  I sent the rear differential and trailing arms to Mike Dyer in Dallas (Classic Corvette Parts)  and had him rebuild my differential with all the best parts.  This meant ultra beefy 31-spline inner axles, 4.33 ring gear, 12-bolt pinion, 12-bolt cross shaft, polished and tuned posi case, huge custom made posi housing caps with 1/2" bolts, thick wall 3" half shafts, 30-spline outer stub axles, and 1/2" studs for the wheels.  It won't be bullet-proof but it will be MUCH stronger than stock.  I also went from a 360# TRW fiberglass spring to a 410# VBP fiberglass spring and put in the VBP adjustable strut rod kit with poly bushings. And while I was at it I also installed a TKO-600 5-speed with overdrive.  Can't wait to try it out on the highway.

Here's what I started with.  This is actually an older picture.  The only think different from this picture are QA1 shocks.

The parts I got back from Mike looked better than brand new.  Not only is the rebuild top notch like clearances set properly in the posi instead of using a spring pack but he sand blasted and finished the parts off with a nice coat of paint.

Here are some shots of the diff after setting proper endplay and gear mesh.  Check out those end caps!  Those are even beefier than the caps you can buy from Tom's.

Once everything was in, minus the spring, I did the rear alignment.  You first set the camber and then do the toe-in.  Here, I'm measuring the toe-in.  Note though that I had to redo this measurement because you need to jack the suspension up on the rotor.  Seems insignificant but raising it all from the trailing arm gave me a different toe measurement.

The best lil' helper in the world.  This is Melissa showing me where the wheel stud nuts will go.
