Yeah I didn’t do a kit. I pieced together my setup and honestly the only reason I went with the t56, it was the best bang for the buck for overdrive behind a bb. I got a quote for one of those gm auto kits from silver sport I want to say it was 8,000. I’ve put together a few cars for that kind of cash and have had a lot of fun with them I couldn’t see spending that just on a trans.
