Best rebuild kit and valve body?

I have used Cheetah reverse manual VB a couple times and like them. For milder builds I like to use the transgo shift kit. I think TF-2 is the one I usually get.
Not much difference in most kits other than type of clutch plates used. The biggest thing is to check things that are not included in the kit like bushings, sprag, etc. The rear band usually has to be purchased separate but some kits do come with both.
Most kits come with the plain jane tailshaft seal. I prefer to buy the correct one with the boot for mine. They cost a few bucks but well worth it.
