I installed my front plate on the black plate holder, but the back has nothing and the plate will just scratch the car--it didn't arrive in the mail flat, but even if it had, it looks like screwing it on would scratch the car anyway, the way the edges of a plate go in a little. I'm checking with Rockville today to see if they got in any of the rear frames, but I don't know if that actually encloses the edges of the plate, so it may not help with my slightly-warped plate anyway. But if I just screw it to the car, it will scratch, I can tell. I'm surprised it doesn't come with a sheet of black plastic like a thinner version of the front plate holder. Any suggestions? Do car places sell something that would sit behind the plate and keep it from scratching the car? Do people just not worry about scratching it (does aluminum not rust?), or use a cut-up old t-shirt, or what? Googling is getting me nowhere but my Google-fu sucks. Also, the "screws" in the back aren't like the front star ones. The back ones look/feel like plastic and have an odd opening--are these screws or is this what the screws go into and I'm missing screws? I stuck a flathead in but it looked like I might damage them (again, felt like plastic) so I almost immediately stopped trying to turn them. Anyway, I figure Tesla can install the plate for me with some special odd-shaped tool they must use, if these are the screws, but just wondering if others have used a flat-head with no problems, or if you had Tesla install your rear plate, or if I'm an idiot and just missing screws. ;-) Here's a too-fuzzy picture of the back screw? place a screw would go in? whatever it is?...I've never seen the like. Sorry if these are incredibly stupid Qs. I haven't bought a car in 12.5 years, gimme a break! ;-) Thanks! Mods: Let me know if you move this so I don't lose it, thanks.
