Stop in for a cup of coffee

Did some panel building on the Studebaker.trying to make less mistakes. Alas, i failed. Guess i have a couple hours left to fiddle with it before i need to wrap it up before vacation. I need to make a u-channel for panels to slip into. A couple of them, actually. The more i think about them, the more complicated it gets.
Been working on a Ford pickup replacing an upper cab corner and it's aluminum and what a piece of ****. Brittle and a pop riveted nightmare.
