Not real sure where to put this but anyway. Does anyone know where to get an adapter bushing to hook up an autometer speedometer to the factory cable?

Can anyone respond to this I too Plan to get an autometer speedo.....I thought it was a straight swap at the cable.

Autometer says to call Speedometer Service out of Milwaukee,WI the
# is 414-463-6660 ,I got this off the Autometer website.

I don't want to pay what I'm sure will be 60+shipping for a bushing. I have one that almost fits. but not quite. Kind of annoying really

All it will cost is price of the call to find out and having the right adapter can save a lot of trouble later.
