Thanks for the add. Had a few square bodies over the years. Bought a new K10 in 1975 fully loaded for the time for $6200. Even the salesman couldn't believe I wanted a/c! 10 years ago I found a K30 with an aluminum flatbed, 454, 4 speed. Added about 60 lights. My latest K30 has a 6.2 diesel and runs great. It lived a sheltered life. No rust, rot or dents. Even in the bed. Not sure what I will do to her, but might do another flatbed.
