Been lurking for years. Finally registered after googling 66 f100 and once again finding threads about it here. So Howdy.
Thanks for the welcome. There is a ton of info on this forum. Not sure what took me so long to register. Some of the metal working threads have definatly changed the way I look at replacing sheet metal. My first resto was a 67 mustang. You can buy pretty much all the sheet metal replacements you need. Just have to cut it off, then paste it back on.
