P30 speedometer cable needed
Anybody got any leads on a new speedometer cable for a P30 Chevy (1987 Airstream motorhome)? The cable on mine is shot and I can't come up with a new cable that actually fits. I need the bit that goes from the speedo to the cruise control. All the parts supply stores (and all the parts websites) keep trying to sell me the CA-3039 but the screw end is way too big, needs to be 5/8" on the OUTSIDE (the CA-3039 is more like 3/4"), or is there an adapter? A part number would be awesome. Thanks for any help!
