As far as the guts inside the bellhousing (and the bellhousing itself), it's all T-5 stuff. Nothing from a toploader works. I would suggest reconsidering the Z-bar set up, which can drive you nuts when trying to fit headers. Additionally, some of them need to be adjusted a lot or they kink and do weird things. I would do away with the Z bar and go with a cable clutch activator, which is very clean, very easy to install and almost eliminates header fitment problems. Check out
www.moderndriveline.com. He sells the cable and the crossmember for your application, as well as everything else you would need. I went with him on my T-5 conversion (into a '61 Falcon) and am very pleased with the outcome.
