And my spring plates still look that way after a year of track abuse...
The zinc/chromate finish is more goldish than the factory cad plating, but you won't find anyone who still does that for a reasonable fee. Just zinc plating can discolor w/ a whitish odization, so the chromate finish is beneficial.
I called around as well. Could only find a place near Baltimore (A1 plating, if I remember) (didn't look as far as Lynchburg). Broke down and called in a favor from a friend in NC who had his plated by a local guy (as a favor). Cost me $25 plus shipping both ways.
Remember, I'm all about the bling that you can't see....
If you're putting in Delrin or similar bushings, the plating helps in that it won't rust and bind, which leads to sqeeks.
