Gene,
I will look into cab mounts and bushings for sure, thanks. I have to take 16 inches out to get the right WB for the wheels to line up right under the fenders so I'm pretty sure I am going to have to make my cut on each side of the cab/box mount or lose the fuel tank bracket. If I take 16 inches from the middle of the bolt on bracket and the cab/box mount they will be touching each other if I could even get it to fit with them both. I was measuring everything today and the front box mount is only about a 1/2 inch off. If I lose the gas tank bracket that is what I will do and just have to use the 57 gas tank, which seems a little easier in my head but this is the first time I have done this so chime in if I'm mistaken. I double checked the measurements from the front of the frame to the center of each wheel to make sure the 16 inches was the right length, used the measurements of the 57 cab, fenders and bed to make sure it would all fit correctly. I know the important part is the cross measurements before and after I shorten the frame but I just wanted to double check everything before I started cutting.
