Hi all, new here. i have a 1993 GMC sierra 1500 with a 4.3 v6. I was thinking about making it 4wd. I had a plan on finding a good 4x4 frame and putting everything i have on mine on to it. Does anybody know if this would work? is there any thing i might run into? would the computers be different? Could i keep the 4.3? can someone give me an estimate on a front drive system and transfer case? would i need to change transmissions?
