Speedometer ?

Here's a cable for '66 & '67 cars. Would work for earlier cars if they had a later trans in them. Not sure what you need to do for a stock speedo drive in a 65 & earlier car.

This one is the correct length. I've noticed most of the big parts houses are listing an 83" long (IIRC) cable, which means you'd have to put a loop in it somewhere.
