Kevin, there is a lot of good info on Moparts doing these trucks. Pretty much any info covering from 48 up to about 57 will apply. There are some variances between the years, but the frames didn't change much and the late 55 cab (with the curved door posts) carried on through 1960.

The frame swap is a big undertaking. If you decide to move forward on it, there are several guys that can and will be willing to help you, including me. I'm on here nearly every night. Gene
