What parts are needed for 4 speed conversion?

IF a person has good knowledge of what is needed, go for it......... I love piecing this stuff together . takes a while. but lots of pitfalls out there. for instance, if you end up with a wrong Z bar, you can cut and weld and make you one. IF you get a wrong shifter box, ie chevy box, well, sell it and get a correct mopar box. buying parts is like Christmas!!!!! yes you will spend bucks buying it all for retail prices at lets say at Wayne's..., but you will get a correctly rebuilt 4 speed, all correct parts,...... yes you can do this on your own... you can rebuild a 4 speed A833 ??? or have a mechanic that can?
any direction you go, if like me, ... I love banging gears and will till me knees fall off!!!! ha
