I was looking at a fresh rebuilt lvl 5 for 1500 that's why it was a choice. Only thing I'm worried about with the 80e conversion is the wiring part and having to get the pcm re flashed. i don't wanna take my truck back to the guy that tuned it, And i don't know if he locked the tune or not. also i have to get another drive shaft, but i would like to get a built one so that i don't have to go through this again. Or will a high speed balance factory (1piece) one with 1350 yoke, be Ok since i had the speed limiter removed?
