If you're mechanically inclined at all or know someone who is and is willing to help, then read this thread:

This guy modified his t56 to work with a mechanical linkage using his standard flywheel, clutch, and throwout bearing therefore saving money on expensive aftermarket parts. He also tells how he modified his crossmember to work with the t56.
If you have any questions about his install you can email him and he will email you back even though he has since sold the car and changed into a Mopar fan.
