HUNTER'S 1978 GMC C15 SIERRA BUILD THREAD
I think I'm going to post all of the problems we found with the bed in stages and then show the repair process.
I'm sure most of you all know what brazing is, I had never heard of the process before and never want to see it done on body work ever again. My bedrails were a bondo mess.. what was it hiding? Brass. Lots of brass. From what I can tell, I guess bondo does not like brazing. While my dad was focused on the bedfloor I took the angle grinder and ground off what I could from both bedsides. The dust was EVERYWHERE!
My guess is the top of the bedside was beat and they drilled holes for the brass to set into in each dent and went to town.. this was a night mare. I discovered them by picking at some bubbles on the bedrails. Stress followed.
