Update, (sorry no pics) I ended up driving north into Whatcom County to the next town, Lynden. Turns out Ethanol Free gas grown on every tree up there, and it’s a nice straight 10 mile cruise up there.
So I gassed up and stopped by Bailey’s Classic Collision. Apparently it’s the shop that does all the work for the custom places around Bellingham.
I told him about the rust hidden under the windshield and described what I’d like done in the future (not concours, but not a get-by job either) and he said that he’d do new rockers both sides, and a passenger door, and the rest he could make work. He said to expect 10-15k for the job and to make it look like it should.
