I was just given a 1976 2wd long bed 1/2 ton, the cab forward has no rust at all, the bed is trashed. I was wondering if it would be an easy swap to pull my blazer tub and put the cab on? I have the 6.2 diesel, is there anything that it will limt me from doing? As for wiring I will just reuse every thing from the blazer tub. I have never done this before, any help is appreciated.
