Could you post some photos of your C cabs. I love those trucks. When I was a kid my Dad & Uncle had a mobile home towing business mostly towing the temp office trailers and portable classrooms. My uncle purchased a new C series short wheelbase (tractor) with a short flatbed with the corners shaved off so they wouldn't crush the trailers in a sharp turn while spotting the trailers into position. As I remember right they took some leafs out of the rear springs because the office trailers didn't have a heavy tongue weight and they would beat up the trailers and rattle the windows out. they also rode a lot better after that. the trucks were equipped with large expandable mirrors for the really wide loads.
That C cab was a cool truck, it had the V8 with a 4 speed and a two speed rear axle. Every summer I would ride with my Uncle or Dad in their trucks all over California. What impressed me as a kid was the view out the windshield, you could see the whole road and more.
Later my Dad bought a LNT with a Cat diesel because they were hauling larger trailers. Then later they bought a really big GMC cab over with a 8-V Detroit with a blower.
The C cab series lasted from about 1957 or 58 all the way up I think into the 80's or early 90's. Mack got the rights to make them also. You may see some Ford looking C's with a Mack badges. A lot of Fire Trucks and Utility companies used the C cabs in one configuration or another.
The good old days.
