I have some photos over in the "Project Journals" section. My topic is "1956 6400 father & son project" I replaced both inner cab corners. I did keep the original top portion of the right side one, and just used the inner section. They both took some work to fit, but once in, I am very happy with them. I purchased one from Classic Parts, and one from Bowtie Bits. No reason for the difference, the parts seemed to be the same.
