i want to change just the escutcheon plate on my stand alone shower (Moen model #2725) from the old oatmeal colored stanadyne version to a new polished brasss version. Where can i find an inexpensive one? The supply stores i checked wanted to sell me an entire kit with valves i dont need, and Moen quoted a price @ $60 for a new plate! Sscrew holes are below center hole at approx. 7 and 5 oclock on the dial. The old plate was 7 in diameter with a 1 in hole in the middle and a square notch at the top of the hole. Thanks.
