Looking to see if someone out there can take a measurement of their truck for me. I'd like to know what the frame width is around the transfer case area on a 67-72 f100 4x4. If someone could give me the dimension from inside the frame rails around the trans/transfer case area that would be great. I'm wanting to buy one of these trucks for a project and trying to sort out my options now. Trying to see if a bw1356 will fit.
