If you buy that kit from stangparts.com i will personally drive out there and kick you in the neck
When I did the swap, I was out a total of $150-200 after selling my AOD tranny. You just need to slowly get the parts together and do it that way, MUCH cheaper.
There used to be a website that had detailed step-by-step instructions on the swap as well as a full parts list, but its no longer up. So I'll try to list the things you'll need from the top of my head. Anyone else be sure to chime in to say the things I forgot.
-T-5 tranny and bellhousing (should upgrade to steel bearing retainer), as well as tranny to bellhousing bolts
-Shifter, boot, knob
-2 shorter bellhousing bolts (or cut yours to work)
-flywheel, with bolts
-block plate
-pilot bearing
-clutch kit (clutch, pressure plate and throwout bearing)
-clutch fork
-clutch fork pivot bearing
-clutch cable (preferably an aftermarket quadrant as well)
-backup light/neutral saftety wiring harness (or modify yours)
-some require modification of the crossmember (mine didnt)
-manual pedal assembly (the hardest part of the swap by far)
I've probably forgotten a few things, but that should be most of it.
Its a very straightforward swap, and you'll fall inlove with your car all over again. I know I did
