I have a '76 fj40, when I got it, it had no motor,tranny, or transfer. I am putting in a chevy 305 w/ an sm420 and 3 spd transfer. also going to run a rockbox. My question is what is to be done with the front shackles? Reverse or leave stock? I have heard conflicting reports, and would appreciate actual feedback from thoes who know. Thanks......
