I am late on this too, but hi fellow illinois'n I think you can get some of the conversion parts from mustang resto on irving park road in Bensenville. I helped a guy install a t5 in a 65 stang in place of the the top loader, they make a templete for the bracket to take the clutch fork and pivot out of the old three speed bell and mounts it in the t5 one by drilling and tapping a few holes there is also a company that makes a peice you weld on the top of the clutch pedal and you drill a hole I think 3/4 of inch in the fire wall and you can use the late style firewall adjuster and cable. Hope this help I am local if you some help let me know.
