well found out that all 3 of my Gauge clusters the speed-o dont work what the hell right. so i took apart the single cam one just to take a looksee. and it's the whole piece that you read i was like wow. so now that i need a new speed-o Gauge i going to get a whole new cluster. and while i was in there i tried to change the miles you can but it's hard lol. nissan makes it were you cant really change it there good lol. dont worry the cluster is trash anyways. no ilegal shit here...
