rat pack - Spring tags is the exact reason I got into this "dacal" stuff about 9 or 10 years ago. When I was searching for spring tags for my F41 69 Chevelle there were none available. The suppliers, and producers of them, only had tags available for the more common cars. A GM bulletin I have indicates a total of 9 different front springs and 7 different rear springs available for 69 Chevelles. Seems to me I saw something regarding 69 Camaros and they had even more.
Anyway, I made up my own spring tags for my 69 Velle. The word started to get around and I ended up doing lots of them for fellow Chevelle enthusiasts. Most of them were similar to my situation wherein the codes they needed were just not available elsewhere. Then the Camaro guys started asking for them and I have done numerous of those as well.
Keep in mind my research was done for Chevelles. Any Camaro input has come from the owners themselves as far as codes, numbers, colours, etc. Mine are obviously not in the form you refer to as far as "texture" of the product. Mine are done on peel off backing paper and are sealed on the surface with clear 3M vinyl. Somewhat glossy yes, but maybe not as much as what you are referring to. Also, the fonts were taken from original Chevelle tags way back when. I use the same fonts for the Camaro tags which may, or may not, be correct based on some of your input.
Here is a picture from my
website of the first Camaro springs I did years ago. My templates are such that any colour of print and background are available. Just thought I would give a little history on the ones I do.
