indy82z Posted October 14, 2020 Report Share Posted October 14, 2020 I have an old 9 bolt Borg Warner rear from an 89 IROC-Z that I want to see if I can get checked out and possibly repaired if needed. I know from research, they use Posi cones unlike the typical 10 bolts that they put in the majority of these cars. Anyone have any experience with a good trust worthy shop local that can do this work? I would not be concerned if it was a typical 10 bolt, but I know these are a little different. I would also love to get the housing blasted and painted while it was there too. Figure the car is going in for a total mechanical overhaul this winter and want to just get this freshened up while it is all apart. Quote Link to comment Share on other sites More sharing options...
