Howard Brown and Sons in west LA, one of the top five shops in town.
They are BMW certified out the wazoo, one of the few shops with z8 cert, great paintwork. Prices are market rate ± 5%
Yes on filing the front-side markers, and the plate holder holes, if you have any.
Might as well get new (black?) grills too.
