Fred
Thanks for the verification on the material. I was wondering if I it could be cut with a hole saw.
Kind of funny,. Since I hadn't been able to find something here I was sure I would find the right material at "The Yard" in Wichita the next time I visited Mom.
Stovebolters: "The Yard" is a great military surplus store and also has literally tons of materials. Nuts, bolts, plastics, aluminum and steel billets, diamond plate, sheet and all kinds of gadgets. Stuff apparently comes from the Boeing, Beech, and Cessna factorys and the Air Force Base nearby.
Fred, I'm looking forward to visiting your vintage chevy shop the next time I'm there.
