A little more progress to post. I sent the last of the cab parts out to be sandblasted. Got them back 2 days later. Very nice to see there was not much rust. But why is it that the only holes I needed for the mirror were brazed shut.
While none of the others were.... Now you see them.
Now you don't.
A little grinding...
and they're all gone.
Everything got a nice coat of Epoxy Primer.
In my makeshift paint booth.
