I've been kicking around the idea of a 1ton gmc with a 6v53t but I just don't think its what I want because with all of the extra add ons I would be putting on it, the truck would look like a topkick when Im done. I was wondering what my options are to find a 80's chevy c60 and put either a 6v53t or 6v92ta if it would fit. Also would want to make the truck 4x4 so would my guess is the 2.5 ton Rockwell front axle out of say a deuce and a half may work for this? I just don't see building a 1 ton up with all the parts that a topkick already has other than 4 wheel drive. Any opinions? Or call me an idiot if Im being un logical haha
