Be careful not to weld too much in one spot or you get the heat buildup you don't want. It takes a while but the mig makes it easy.
Drilling holes through the top panels, and plug welding into the bottom layer gives the "spot weld" look you can see in a few places. That is a handy technique.
Hippy dippy days with the poontang panel! I bet you got some stories there!
That's useful advice. The Eastwood web page tech section had similar advice though not as detailed as yours.
The 6 cylinder engine and three on the tree was the most common configuration back in the day so I think you made the right choice. They were great trucks and a common sight when I was a kid. I look forward to following your progress.
