I thought Chevrolet had the trailing arm and GMC was leaf, but any combination is possible given different factories and specifications and the fact that many of these trucks have already been rejuvenated a time or two by now.

With a '52 shortbox on a trailing arm frame, the stock c10 springs don't even begin to compress and it sits way high. Springs from a late 60s early 70s chevelle will bolt right in and are a lot softer. my current set is from a chevelle wagon which seems about right, it sits low and can still have some weight in the bed.
Full disclosure, my '52 is on a '65 trailing arm frame because s10s hadn't been invented and mustang IIs were worth new car prices when I started this project. I'll do a build thread someday once I have some miles on it and can say something useful about how well it works
