Rob,
Had tried the ratio adapter approach and found to the best of my Knowledge that Stewart Warner no longer makes them. They had them listed in the last catalog that I received from them but not in the newest catalog. Dug through all my stuff and found 5 or 6 different ones; modified one; and got it close for now. I think that we will all have to look into electronic speedometers sooner or later! Just rebuilt the electronic drive in my Cummins Dodge piece of cake.
I have been in hiding for awhile due to a thief that was stealing from me for awhile before I figured it out and laid out to catch him!
If The new "Texas Castle Law" had been in effect he would be buried instead of in jail.
I have one of those A 833 overdrive boxes that I have been eyeing also.The "Texas-Beast" is finally getting new wiring!(Cummins Powered 49 one ton Chevrolet Pickup)
