so i swapped in my 5-spd cluster today (conversion is RIGHT around the corner), and also painted the bulbs amber, but thats besides the point.
i was concerned that the odometer was going to be off, but heres what i found out.
if you remove the the front of the cluster (the clear plastic), then remove the black piece of plastic trim, you can turn it over, remove the 4 screws that hold the odometer gauge in, and swap that into your new cluster.
so for those of you changing gauge clusters, you can still keep your odometer.
maybe some of you know this already, but i didn’t.
