I bought a hydraulic slave kit from NOVAK for my T18A swap in my YJ. They had just come out with a kit for AMC bellhousings when I was trying to figure out how I was going to do it. I am assuming that you are running a Ford 435 with an AMC b/h, correct?
I haven't completed the YJ to test it out, but I don't see any problems.
Novak was great to deal with as well and their tech guys were very helpful. They had prompt responses to my questions. I was not impressed with Advanced Adapters as I have not heard back from them since I sent them a couple questions approximately 6 months or more ago.
