Well, that settles that subject! Thanks guys! I wasn't getting any input from any one i know around here so i was kinda torn! So, how hard is a POSI unit to install? I'll proabably install it with a new ring/pinion, but how do i know if i have the 8.2 rear or the 8.5 rear? I know it's 10-bolt and has 2.76 (or is it 2.73) gearing, but that's all. Are there casting numbers i can check? I want to get a posi setup with 3.42 or 3.55 gears (so it's still highway friendly), but i don't want to drop $100 into the rear end when the whole car was only $150, and the engine/trans swap was only $200. Should I just keep my open diff rear end for now and work on getting the rest of the car up to being powerful enough to actually NEED a posi unit? Right now I run a stock 83 305 v8 through a 1.76 geared Powerglide. It's not a drag car, cept on weekends occasionally, it's more of a daily driver street car. But it does do some racing.

Also, anyone know if the rear outta a 78 or 79 camaro will fit? or how about an S-10 or S-15 jimmy? 80s model.
