Rebuilding TH400

I'm gonna start jumping into the Turbo 400 in my CJ7 and rebuild it myself. What I'd like to know is what rebuild kit do you guys recommend? Also, which torque converter. It's not going to be built for performance, I just want recommendations for quality parts. The only thing I'd like to ''modify'' is the shift points, it shifts too soon for my liking.

I have always used Transtar parts and PDQ converters quality parts ,as far as shift points the T400 has an adjustable vac modulator you can turn the screw in or out to get the desired shift points,if it still shifts to early you can change the springs in the govenor.
