I bought the cheap stamped out aluminum trim rings and then removed my cluster and affixed them with thick super glue in a horizontal fashion. The cluster went down on top of the face-down trim ring and I held it there for five minutes so the glue would flow along the inside rim of the ring, not drip down the face of the gauge.
They look great, by the way. Everyone comments on how cool they look too.
When superglue interacts with plastic it melts it and it can't be cleaned up with goo gone or any other product. It's toast. Literally.
Buying another cluster with the same part number is your best bet. Using just the face of it is smart too. Then you don't have to send it to Palo Alto Speedo in CA to have the odometer fixed.
Replacing gauge faces is tricky too. Getting the needles back on in the same place was like pulling my own teeth (painful AND time consuming). I must have put the cluster back in the car and drove it around the block four times one night to insure all the needles were in the right places.
