Howdy all!
I did something similar with my hubcaps, and they worked great. Unfortunately, I lost two of them because of user error in shops. This is what happened. One of the wheels has a small rectangular box on it that causes the hubcap not to mate properly. (I think it's related to the Tire Pressure Module but I'm not sure.) I notched one of the hubcaps and labeled them to match the tire rims. But two shops ignored that and just slapped on the hubcaps randomly. Twice caps without notches were put on the wheel with the box, and they flew off after a hundred miles or so.
I'm about to make a new set and am going to do things slightly differently. This time around, I'm going to drill six 1 3/8" holes through the pan, (5) for the lugnuts, and (1) for the air nub. That means the wheel can be serviced without ever taking the hubcap off, and I'm going to write DO NOT REMOVE HUBCAP on it. That's faster maintenance and should ensure the caps stay matched to the rims. It also provides some minor airflow to aid in brake cooling, as well as dust and debris removal.
This is just one of several examples where I've had to tweak a mod in order to make it easier to service. I've been writing service instructions in Sharpie black right on the mods now, so that it is less likely mechanics will mess things up.
