Small wonder, as there wasn’t much more than a gum wrapper tying the sub frame to the truck frame.
Remains of an air compressor motor mount plate found hiding in the weeds. I almost used this stock the day before on another project. There is just enough metal here for two brackets.
Test fit.Bowling a spare. Holes drilled oversized for future realignment to the truck frame.Finished. Still have to do the other side at some future date,but at least the bed won’t tip over backward any time soon.
