Spedo cable adapter.
I could sure use some help with this one... There is a small metal speed adapter... thingy that plugs into the transmision on my 79 excella 28". When my spedo quit working I figured out that this was broken but I threw it out assuming that if I removed the broken cruise control unit and got a new cable, I would not need this "thingy". Well, wrong, and now I need to find out the exact model number to make it work.... any ideas?
