70-72 Rear body panel trim

[novab]

Yea, I tried that they are maxed outward as far as they will go. I'm debating on carefully grinding the ends of the panel. I just don't want to chip the chrome. It's a very nice panel from Trim Parts. They said it is made from original GM tooling so I assume its the correct length. They measured another one and it was the same size. This is a very high quality restoration and don't want it to look bad though. I wanted to the fender louvers and hood louvers but without the rear I don't think it would look correct. Any input on grinding the ends of the rear panel without chipping chrome?
