Hey guys I have a 92 RS with a 305 TBI and a 700r4. My rearend is stock and i wanna go with a 3.73 set. I would also like to go posi. I know SLP has a good posi, and gm motives are good gears. My question is which posi from slp do i get and when i get the gears do i get a 3 series? 26spline? I honestly have no clue what i'm looking for. I am also looking for a good place for install. I live outside of chicago, around Naperville. ANYONE have any ideas for me? Thanks
