It looks like it hasn't got into the windshield header or the door pillars yet. The rust has been creeping upwards from the front corners of the rain gutter into the roof skin.
It'll start creeping down into the pillars soon if I don't get a decent repair done.
It'd be cool if I could find a new roof skin repair panel but I haven't found any through the on-line parts suppliers.
A solid used one would work, too but I don't think a junk yard would even have a '65, much less let me cut the roof off one.
Anybody got a cab they're cannibalizing?
