After going over a good pot hole in my '59 3100 the Speedo started working again, but... the needle is erattic in that it swings 10 or 15 MPH.
Cable?, tranny gear, Speedo? any help would be great. I'm new to restoration but My Dad bought the truck new, I learned to drive in it, and I'll do what it takes to keep it on the road.
