Hi,
I replaced the stock 11" clutch with an upgrade to a 12" model. It was a direct bolt on to the existing flywheel. Here is the info:
Made by RhinoPac, Part number 07-050A 90206. There number is Technical hotline 1-800-528-6743. Total for the kit was 258.00
The only way I know of to tell the difference between a FE and an FT is to measure the crankshaft diameter. The FT is larger. Sorry but I can't remember the exact dimensions.
Hope this helps,
