has anybody put a complete turbocoupe rear under a foxbody and used the cobra r's?i know the rear is a little wider but this winter that will hopefully be my project.my 3.73s are shot(previous owner had a poor installation done)an open diff. sucks also plus i wouldn't mind the rear disc upgrade.i'm not worried about the quads because they were gone when i got the car,just hoping my cobras will still fit.thanks
