Thanks for the replies guys. I'm not sure if it is "drop in" enough to get my dad talked into it. He's not as into cutting things up as I am
To each their own. The TKO600 drop in kit might be the winner, even though I'd rather he went through the work for a T56 Magnum. If I could just get a mechanical linkage bellhousing for a T56 I think I could make the rest work...
