Trim Ring Difficulties

I rarely visit FABO anymore but just happened to come on today. Hemijj no I never solved the problem. Yesterday just for kicks I decided to install one of the rings that came with the car (in the pictures) and it slapped right on like any normal trim ring would. Eff all of this "correct" stuff for now. I just finished polishing all my moldings so I'm gonna do the same with the rings that fit. I need to finish this car after 15 years.
