And before you ask, yes, I did ask Tsutarja495 about this beforehand via Discord, and he gave me the a-okay. Even before 0.23 came and introduced PBR materials, I spent some time on and off making these additional changes. But fortunately for you people out there, I've been working on an updated version with more parts and some bugfixes. After all, it hasn't been touched in a long time.
It seems people still want an updated version of the S550 Mustang mod.
