Hey im new to the HAMB and had a few questions regarding the 53-56 f100 frame. I have a 55 f100 that is my daily driver with a I6 223. I want to put in a 351C. Im thinking about purchasing another frame and getting that all set up with an ifs and discbrakes and installing the 351C into that frame and when its all ready just switching the cab over. Will my 55 f100 cab fit onto the 53-56 frame?? and do i need to box the frame at all for the 351C?? Plz help!!!
