Here is one that I did. The cab is december 1930. the running gear is november 1928 . We shimmed the cab. It didn't take a whole lot but it was enough that I had to use longer bolts from the local hardware store. I had to elongate the holes in the front cross member to align the 31 radiator. We used a new repro bed, back fenders, splash aprons and running boards. All and all it worked out fairly good.
