The easiest route to go is find a turbo coupe thunderbird and get the bellhousing,
trans, and all the associated cabling for the hydraulic clutch setup.
The pedal assembly can come from any foxbody.
Remember that you will need to get the right speedo drive gear that is in the
trans that will match the rear diff gear. The '87-'88 TCs had a 3:73 for the stick. Summit, Jegs, Ford, etc has them. They are color coded.
In addition, if you swap out the fluid for fresh, make sure you use ATF and not gear oil.
