I am new here and hoping for some help. I am frame swapping my 65 GMC with a 99 GMC frame. This way I can have a little stronger frame, disc brakes, and a nicer riding suspension. What are some things I might have issues with in the process. I plan on using the brake booster and master cylinder from the 99 with a stand alone abs module from speedway motors along with all the brake lines. I am using the gas tank, sending unit, and fuel lines as well. I will also be using a few other things but I am currently concerned on the struggles I may have swapping the frames. Any help in much appreciated. Thanks.
