I use the QT bell w/jerico. You should have plenty of tunnel clearance (bell) since I believe they use the same bell just weld on different adaptor plates (not certain). Don't know about T56. The QT limits you to a 130 tooth flywheel which should be no problem.(I run a 10") If using stock linkage (or external slave) pay close attention to the pivot that is supplied. It does not locate the fork/TOB properly. There is no pocket to locate the nose of the starter but I've had no probs.
Sounds like a cool project. Have fun
