R model electronic speedometer

Looking for used electronic speedometer for superliner

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.

Ok thanks.  Looks like the bezel is a little different

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
