This is a question that popped in my mind. In My early 89 gt, I have that damn 85 mph speedo. Can I buy the 140 out of a 90 GT and just plug it up to my existing wires for the 85 mph? Or will I have to change the drive gear in the transmission too? I was originally going to buy a 160 mph from autometer and hook it up, but I have a friend who is selling his whole dash cluster out of a 90 GT. Are these stock speedos even accurate? Thanks.
