Just bought a 140 speedo from MAC, "white face", i have an 88 so its upgrading from a crappy 85 speedo, what do i need to do to make the speedo accurate??
Mustang5L5 said:All you need is the speedometer mechanism itself. You don't need to change clusters. Just swap the mechanical parts and install your new faces.
You can use a speedo from any 89-93 car in this case

There us really very little to it. No recalibrtion needed if you find the 140 speedo becaue its already calibrated.
ram360 said:So I'm assuming 89-93's have 140mph speedo's? If your saying to just remove the mechanism from one of those isn't it just easier to just replace the existing 85 mph cluster w/ the 140 and just throwing the white face over that? IMO that's easier (but maybe I'm not understanding what your saying) For what it's worth I never come across the 140 clusters very often, and I see them go on ebay for like $100+.
