As you may or may not know 88 mustangs have 85mph speedometers. Well since it's looking like I probably won't be able to get the Florida 5.0 custom gauge cluster I've decided to get a 90-93 gauge cluster to hold me until I can get the Florida 5.0 set. So do I need a 90-93 specific speedo cable to use the 90-93 cluster? I feel like this is a stupid question but I was always told the only stupid question is the one you don't ask.
