i'd say 7-9 depending on who u are. the guages in our car arent the easiest to remove and reinstall. we did my brothers civic and it was a breeze we had more trouble putting the cluster back in than we had taking it out and installing the guages. also be careful how u ground the wires. my brothers own kept going out on one side cuz the wire wasnt grounded correctly and we ahd to open it up again to fix
