hi all, i have a 53 chev 3100, i want to build a 4 wheel drive, which frame should i use, also can i swap to a GMC grille and hood without changing fenders.

On the gmc the hood grille and core support are different from the chevy so you pretty much need the whole front group. I have never converted one to 4wd so I'll leave that to someone whos done it. I have seen the conversions and they look cool just never done one myself.
