Go to DIY section. The bulbs you'll need are pictured in my opening post and are available at Radio Shack.
The only thing missing is a reference to 2 mounting screws on the cluster itself. In my '96, I had to remove 6, not 4 mounting screws (See picture # 7 of the link) I had 2 mounting screws at the top of the cluster in addition to the 4 pictured....ALL easy access!
