Such a simple mod, followed the instructions in this article:

Takes a T-10 bit for the removal of the gauge cluster screws. Some members have reported trouble getting the cluster open. It takes some patience and coordination, and a flat tip screwdriver or similar tool, but the cluster will open. I then slipped my large rings through the round openings. Turn it the right way, it doesn't even bend.
I did need to use an exacto knife to shave some plastic off the inside round plastic pieces that hold the rings, because the fit was too snug.
Total time about 15 mins. Got the rings off ebay, they appear to be OEM E39 parts.
Love the new look.
If anyone needs help with this install, please PM or email me!
