120 MPH speedometer

I have a 79 F150 with a 80mph speedometer. can anyone tell me where to find a 120mph and what would have to be done to calibrate it.

No 120MPH speedometer...the highest was 100.

Find an 73-77 Ford truck, and you'll find one (if hasn't robbed yet). I think you have to change speedo cables. Not sure.

Note: 78-79s came with silver speeods with black background, while the 73-77 is all black.

Go to http://www.projectbronco.com/ There is a tech article about swapping in a 100mph speedo into a bronco - same as your F150. Looks like an easy deal...
