Shift Kit help please

Tomarros pay day and i wanted to order a shift kit for my 2wd 1st gen with the A518 nonlockup 4 speed, but any dodge tranny advivce will help. I was planning on ordering the TransGo TFOD-DIESEL kit, but after looking around, thers also the TFOD-HD2, the TFOD-JR, and also B&M, TCI, Turbo Action, Hughes, and more. I DONT have the money for a complete valvebody, so dont bring that up. What i want to know is what i should get, and whats involved. I havent found any instalation threads or directions yet, but im still looking. Links would be appreciated.

Please help, thanks Jake.
