Bought a 91 CRX Si Cluster

Hey guys Im finally ditching my old Automatic cluster in my Civic! Anyone have any suggestion for me about switching clusters? Is there anyway to change the miles on the cluster without removing the plastic cover?

well,,im not sure if the crx si speedometer is the same or not with your old speedometer,,but i will tell you what i did when i swapped my clutster. In the new cluster i bought i unscrewed the speedometer from the back and pulled it off,,i got my old speedometer and put it in the new cluster and it fit perfectly:devil:
