W124 interior swap - window trim

[moruzzi]

OK maybe I need my head examined, but I'm thinking of doing a full interior swap on the 400E I just picked up. It came with a tan interior and the parts car I have has a grey interior that is actually in slightly better condition.

Anybody else do this?

There are excellent threads on headliner removal, seat removal, door cards, etc. The think I have not found is info on the window frame trim. Anyone have any advise or pointers? Are they glued on or just snapped in place, does it all become obvious if/when you remove the door weatherstripping? Figure they must get swapped in body shops when doors get replaced.

Any other advise on a full interior transplant?

Thanks
Paul
