Deb, If you can't get the SS as Loc suggests. (first choice IMHO)

You are conveying here that you want the details very correct. If there are four of these bezels then you would be best to replace all four with new and keep the old as spares or to offer to others.

If you go the buy plain and have them chrome plated also buy more than you need ( things go wrong ) and choose the best product for YOUR bus. Be sure to find a highly qualified shop that is willing to give you the result you desire.

There are different types of chrome plating, each giving a different "look" and having different life expectancy.

Some categories of plated items are: Building hardware, plumbing fixtures, hot rod components, motorcycle components, antique car and boat components.

Ask around for recommendations and see samples of the shops work.

Caution!! Many plated parts are ruined in the polishing department!

The extras I am confident would sell.
