Because of various topics in this great forum, I finally had the balls to install chrome gauge rings in my instrument cluster. I bought the rings on ebay from eurosportgarage and it was a great fit. It simply snaps in. Twisting the tabs in the back of the cluster was the trickiest part. When the gauge was open, it took me no more than 10 minutes to install and snap back in. Here's the picture after the install:
