Dumb question (maybe you addressed this?): Did you use a sheet metal gauge? I bought 22 gauge for the 1960 panel repairs that I'm doing and got my metal from a scrap heap next to the metal shop's cutting machine. The metal shop guy had a circular 3" Diameter thin metal disc with radially arranged slots cut into it of varying labeled sizes. The gauge's slots were slipped over the edge of the metal till the right slot was found to fit. This would be the reverse of a feeler gauge, I guess. No moving parts, so should be really cheap. -Kenyon P.S. - The segment of 1960 Imperial that they tested said 20 gauge and was from a single wall quarter panel near where it was rusted, but the sample that was measured was un-rotted and accurate as far as I know. I went to 22 so that I could form it more easily with my rudimentary experience and it seems fine for smaller patches. > > Does anyone have any literature that talks about the actual guage of > > metal used on the bodies of Imperials?
