The front plates never have expiration stickers, so having no stickers would be as unrealistic as having them in the front and the back. Unfortunately that's something that can't be changed with a mod. The current textures will get an option without any stickers.
I will make the retro pack as well then, with the 1987 plates instead of the current ones. The stickers will be a mix between the two styles of older stickers (this and this) with different colors and no year. The exempt plate will just have the SA EXEMPT text with the old font, like the default one.
The 1956 plate would probably be easy, but the 1942 has a different format, I'm not sure what would be the best way to do that. I'll consider seperate textures when the two complete versions are released.
Edit:
Well, the real question is: When will be the LSPD slicktop Caprices released?
That's the main question
That's not a question for this thread, though
