Hey everyone, I'm new here. I was hoping someone could answer a couple questions for me. I have a 1987 Chevy G20 camper van with a 6.2 diesel engine and a 700r4 trans. I am interested in converting it to 4x4. I found a 1975 Chevy G30 Van for sale with a Pathfinder 4x4 set up on it. It's quite a few hours away, so I haven't been able to look at it. I am wondering if I could directly swap all the components over to my van, or if there would need to be a bunch of fab work done? Thanks!
