The trans-go shift kits are very common. The B&M Trans Pack is nearly the same as the TF-2 kit, but I think it costs more.

As mentioned power level and use, along with other mods may determine what materials to use. When I rebuilt the 727 for my near stock 318 (when I was working at a trans shop), I actually used some stock type frictions and steels (used) that were in near new condition that came out of another trans we were updating with the Alto frictions/kolene steels that was going into a drag race car.
