I've had some LCD issues in the past year, decided to go in on the refresh kit from BATEE.com, and I'm up and running like new. Not a hard job to pull the cluster, and the refresh is a good off-season (or weekend) project.
This may be all you need...

I needed the LCD connector as my panel was intermittent. I also opted for the replacement bulbs, LCD resto, and tach calibration while the cluster was out.
