I’ve tried some of the local shops and but none match the one that came off of the truck. I think it must be original as under the several layers of paint it has a little of the original blue. The rubber is nicely drilled for the window frame bolts and even counter-bored for the bolt bosses on the diecast frame. I ordered one from a mail order place but it did not match either.
Looks like I’ll try the WD40
