5 Speed Conversion

I have a 94 Cougar XR-7 v8 and im looking to do a 5 speed conversion. I have a borg warner T-5 tranny i'm looking to install. I'm taking the clutch pedal, linakge, master and slave cylinders off of a super coupe as well as tranny mounts and cross member. Just worried about rear end. Don't think it's geared for it. Was thinking of a ford 9" but not looking to get rid of irs. Any ideas would be helpful.

Re: 5 Speed Conversion


You should have an 8.8 rear already. The ratio might be 3.08 with the 4R70W trany.
Most guy's install the M5r2 that comes with the Super Coupes.
