Sorry I can't help you on the TC. Make a build thread with lots of pics please. I'm really interested in seeing what route you take with this. I'm swapping a SBC 383 with TPI and a 700R4 from a 1990 Vette into my CJ. Luckily I already have a Dana 300 tranny so I don't have to worry about that issue.
Do you have emissions where you live? If so, how are you going to deal with that? We only have emissions here for 96 and newer vehicles so I'm not willing to mess around with my TJ.
Good luck with your build.
