Hmm... Billy T, I was looking around on ebay earlier, try searching for "gauge pods". I did find some aluminum and stainless gauge BEZELS for an 80-96 Bronco/F-150 stock instrument cluster, but not any panels to insert aftermarket gauges into. I think the metal you use to mount the gauges should be thick enough that you cannot bend it easily with your bare hands, but doesn't need to be thicker than 1/8". I usually rummage through the scrap pile for parts like this, but you should be able to find new metal at most harware stores for little cash. Any of the gauge makers like autoMeter have templates you can use to mark and cut the holes out of the metal. If you just need a flat surface, i would go with a bit thicker metal. if you have to contour it, go for the thinner stuff like 18 ga. sheetmetal of aluminum. You can bend the metal using a vise and hammer or pliers, or fab your own metal brake using lumber or 2x4's. JSM84
Edit: I made two covers to fit where the factory A/C junk used to be on the firewall in my 84 Bronco. I used 18 ga tin, which was easy to cut and drill holes in. Then used screws to secure them. Look in the upper-lefthand corner in this pic. the panels are a darker shade of blue. Maybe you can see how thin that metal is compared to a street sign thickness:
