Will the 03 cobra factory posi unit work for the fox body 8.8 rear ends? I am looking for a 31 spline (rebuildable unit)posi for my 92 coupe. What other ford applications will work for my year that have a 31 spline unit in them? Thanks

This is why I asked the question. I just wanted to make sure before I bid.

Yes the 03 Cobra carrier will fit right into a '92 housing. The 03 Cobra uses ABS so there is an ABS ring on the carrier but it comes right off with a hammer [Wink]

2stangs69-91 just put one of the 03 Cobra 31 spline carriers in his '91. Works perfectly

What air pressure do you run at the track and how well do they hook?
BTW, Sweet ride

i think they hook great, and all my friends run them too. i picked the qtp's because they have smaller section widths than ET Streets while maintaining a decent sized patch. They also do quite nicely on the street. I run them between 12-15 psi.
