Exterior panels were typically 22ga, but most people here will tell you it was thicker!

22 is very thin. if you are making patches i would go with at least 18. i think most late model stuff is 18

All I can say is that I also mic'd them and there is no way any exterior panels of any muscle era mopar are 18ga.

....go ahead and use it for patches, but it's thicker than original

FWIW:

Cold Rolled Steel thicknesses:

- 18ga = .0478"
- 20ga = .0359"
- 22ga = .0299"
- 24ga = .0239"

Satin coat or galv. sheet

- 18ga = .0516"
- 20ga = .0396"
- 22ga = .0336"
- 24ga = .0276"

Had I known there was going to be this much confusion and controversy on the whole sheet metal thickness thing, I would have taken a micrometer to every panel in my car when it was down to bare metal.....oh well.

Don't forget that metal from the mills can vary by a though or so and not all micrometers are created equal; if you're using some pce of crap from a box store that cost $7.00, you may not be getting accurate measurements.

my 4 cents;

I checked the thickness on my 69 coronet 500 and my 69 super bee and my buddies 69 RR with two different gauges and they show 18 ga.
