I contacted a company called ECS Automotive who are renowned for their 100% accurate Mopar reproduction decals and asked them if they were interested in stepping outside the Mopar arena for my project. They were quite interested as they are looking to expand their catalog of decals with GM stuff. I cant say enough about these guys. There products are 100% exact compared to the crap that is out there. I previously had one of those "resto outlet" decals that was just pathetic: wrong size, wrong font, wrong spelling etc.
The guys at ECS even reproduced the exact material and process that they were originally made in. The factory emissions decals were clear plastic with black and white printing laid on from the back side of the clear plastic, not like the modern spray printed version the "resto outlets" sell.
Their phone # is (636) 207-7767

By the way, they are now actively looking for other decals to reproduce: if you allow them to use your original decal(s) for a pattern, (which they send back to you, of course) you get the new reproduction one(s) for free.
Here is a comparison of my original and the ECS prototype (which actually had some preproduction flaws which I couldn't see but they said they altered after this version) They said there were something like 15 different fonts used in these decals and the "other" decal makers just use one font for everything...and it shows.
