1. the 94/95
trans has an input shaft that is about 3/4 of an inch longer than the fox one. YOU CANNOT CUT THIS SHAFT DOWN. You can buy a new fox or used fox shaft and easily swap it out. Try hanlonmotorsports.com or astroperformance.com for a new 87-93 fox input shaft.
2. 85+ t5's are all world class, 85-89 are all the same, 90+ are all the same rating with the exception of the cobra
trans, which are rated maybe 15 torque pounds higher.
3. When you change to the fox input shaft, you'll need the fox bell. You can't swap to the fox bell without swapping the shaft too.
4. I find way more complications and cost than what it's worth to convert to hydraulic. Too much $$, and too many parts. the pedal effort often can be higher, and is too neutral. A good clutch cable gives you a direct mechanical linkage to the clutch, and gives you a much better feel and better reliability.
5. You can have your header tube relocated by a competant exhaust shop to clear the clutch cable at the bell. I did this, cost me $100.
6. I HIGHLY suggest the mustangsteve clutch cable setup, it's a lot better, and uses a clutch cable that can be bought cheapely anywhere. His setup has less moving part at the pedal assembly and won't wear out, unlike the ron morris setup. If you're running longtubes, don't use the fox clutch cable, use the 96+ adjustable mustang clutch cable with the mustangsteve clutch quadrant.
