My 95 Trans Am has a bad cluster(the oil pressure gage is broken). I have another cluster out of a 95 Formula. If I use this cluster but change the backing from the 110 mph Formula speedo to the 155 T/A backing will the speed still read out right or does something need reprogrammed? Also is there any way to roll the new clusters milage forward to match the milage of the T/A cluster? Thanks.

 

Id like to know about moving the mileage as well. I've got a new cluster from a wreck, but it has numbers waaaay higher than mine.
