Aftermarket Speedometers / or a 90-93 Speedometer? please help

[Bonez201]

Hey i was wondering. The speedoo in the 87-89 GT has the louzy 85 MPH speedometer. I would like to change it, and maybe put in a nicer one that goes past 85. Or a 90-93 style speedometer which goes to 140.

Would this work? Can anybody help me out with this? Thanks

Stock type 140mph guages are available.

Take a 90-93 140MPH speedo, remove the "guts" and swap it into your cluster.

Transfer the stock gauge face over or buy some overlays.
