Once you get the cluster out, you can remove the lens and the rear cover by removing the screws around the perimeter. My old '91 had the same problem and I found some broken plastic in the odometer, which caused it to quit. I was able to re-work it with some metal strapping and a small screw or two. As I recall, it was the retainer for the spring on the reset button and it went together pretty easily. I hope yours is just as easy.
Good Luck and God Bless
