I found a source for these and have about 25 for sale if anyone is interested. The price is $37 a plate which includes shipping in the USA (shipping outside the USA is extra).
These are high quality silkscreened parts on aluminum plate and pre-punched with rivet holes in the corners. They will accept a 5/32 rivet and caution should be used when riveting to fiberglass to avoid possible fiberglass cracking (consider a soft aluminum or a plastic rivet).
I can have them etched with your VIN number and assembly date for an additional $12 per plate and this will add one week to the delivery time.
PM me for payment information if interested.
