Alright some further updates this week...
Since I don't have a driveshaft for the car and I'm going to literally be making roughly double the horsepower compared to stock, I decided I'm going to install a stronger 1350 yoke on the transmission and rear end. After speaking with a welding and performance shop, I'm going to get the axle tubes welded to the center section and install a crush sleeve eliminator while the 1310 is out and getting swapped for the 1350. I would love to do the axles, gear and differential but it's just too much money for me to spend right now.
Step 1 was take off the wheels....

Since I'm having a shop do the welding, the guy at the shop said it would be cheaper for me overall if I do as much prep work for him as I can. I got as much as I can degreased and started some light wire wheeling in the area that will be welded. I plan on doing more before I drop off at the shop....

Axles after I degreased them...

Bummer....after pulling out and degreasing, I looked closer and found out there are two different axles that were in this rear end...

Since I'm converting the car to 1988-1992 1LE front rotors, which have a metric wheel stud, I decided to buy some GM Genuine metric wheel studs along with black lug nuts for a 1992 Trans Am on Rock Auto. I'm pretty excited about this part. The drum brake rear end also has short wheel studs, so installing the 3rd gen metric studs should bring everything into correct specification.
These are the "now garbage" wheel studs that came out. Glad I took it apart and found the mismatches.

Since the axles were broken down and cleaned, I decided to throw some silver engine paint on them. Came out nice for "quick and easy". Now I'm waiting for axle studs to come in the mail.

After the axles were prepped, I decided to degrease, wire wheel and paint my sway bars. Factory is black. I like most things to be stock-appearance but I figured I would try something different with the silver instead. Original GM sway bars and PTFB rear drop links painted silver....

1981-specific WS6 brake booster and aluminum/plastic master cylinder. Quickly disassembled, painted and greased. I would love to send this thing out for a zinc coat restoration but rattle can paint will have to do for now.

A few words....
I'm pretty excited with how this rear end, suspension and brake system is coming together for being basic parts. 1988-1992 1LE front rotors, 1981 WS6 booster/master cylinder, 1979-1981 rear discs/calipers, 3rd Gen GM wheel stud conversion, Kore3 black braided stainless hoses, Hawk HP Plus pads and GM 3.42 rear gears. For the suspension/steering, I have an original GTA/IROC steering box, PTFB steering shaft, original GM WS6 sway bars, PTFB HD drop links, PTFB GT Pro leaf springs, solid leaf spring plates, Detroit Speed front springs, AFCO Racing control arm bushings on the stock arms, and non-adjustable Bilstein shocks. Wheels are '84-'87 16x8 convex WS6 with BFG Z-rated 255/50-16 tires. I like this combination, now that I think about it more, as it will be a good representation of originality, GM Performance and very slight modern enhancements.
