What kit(s) to buy for a mild 904 rebuild?

Hi, I am currently rebuilding a 5.9 magnum for use in my 71 Scamp. The scamp is a slant 6 auto car. I also have a 904 to install with it, and I will be reusing the slant 6 torque convertor.

This is a budget build focused on drivability, with a little extra performance... but I would like to daily drive my 71 Scamp. No headers, very mild cam regrind, small carb, functional A/C, going to use the air cleaner heating tube that pulls hot air off the exhaust manifold, etc.

Anyway, I am about to rebuild the 904 trans. I have the 904 book by Tom Hand.

My question is, what rebuild kit should I get for it, knowing the kind of car I want to build? And what shift kit should I get? Anything else to add to my shopping list? Thanks in advance!
