Well, I decided to try the chrome mylar gauge housing/carrier trim stickers. In the past I tried close-to-chrome paint, but that didn't look too good. I also bought a 'correctly restored' gauge housing that had the heat stamped chrome like the original, but the quality was very poor. So, I restored my gauge housing and applied the chrome mylar stickers purchased from Rick's.
Installation was a little tedious, since you need to make sure to properly align these little beauties. They don't have much 'give' to them at all, so the positioning needs to be spot-on. I removed several very small pieces of the backing to allow for repositioning the trim. When they were in the right spot, I removed the backing in larger sections and pressed them into place.
They look good. I'm very happy with the way they fit & look.
Here is a picture of the finished product:
