I have had a lot of old cars and also done panel fab work on many more and I have generally found that the metal up until the late 60's is 19 gauge. The metal gauge mentioned by another member is the very best way to measure metal. The metal will also vary slightly in thickness depending on the process used to form it initially. The real key is that you want to really fit the panel well and butt weld it in, not overlap it as some suggest. If you would like more on this concept, email me off line Regards RR Richard Routt rar@xxxxxxxxxxxxxxxxxxx 1-877-863-6990 -----Original Message----- From: mailing-list-owner@xxxxxxxxxxxxxxxx [mailto:mailing-list-owner@xxxxxxxxxxxxxxxx]On Behalf Of Kerry Pinkerton Sent: Monday, March 31, 2003 1:37 PM To: mailing-list@xxxxxxxxxxxxxxxx Subject: Re: IML: Metal guage No I used calipers. The problem is that with paint on one side and 'stuff' on the other, i can't get what I consider to be an accurate reading. I'm sure this is documented somewhere. I'm confident that the 57-66s are 19 or 20 guage with the once piece front caps on 61-66s being heavier.
