The C500 series was Clarks mainline truck for many years. They had their quirks but all in all a very tough truck. When these trucks were built Clark had over 30% market share. Clark redesigned their mainline trucks in the late 80s. The new trucks were G series trucks. Very few parts would interchange. The boxcar trucks have a special counterweight, it is taller to decrease the turning radius so the truck could be used to load boxcars. The rest of the truck should be the same as a basic truck.
