R model electronic speedometer

stutz 712

Recommended Posts

Something is niggling in the back of my mind that Mack used the Prestolite Treckstar speedo like IHC did. If that is true, I have a used one. I know it worked when I had it in a truck a few years ago.

It's yours for the postage if you want it. Face is 4 7/8 OD fits in a 4 11/16 hole or there abouts. Dip switches on the back to adjust for tire/ratio, has extra wire for Eaton 2 spd (leave disconnected if you don't need)

 I has no "name" on the dial
