My dash is so nice including speedometer I’d really like to continue using with a C4 rather than an aftermarket speedo.
If the threads on the back of the speedometer are the same as a 39 truck speedometer the 64 falcon/ mustang C4 cable fits and is the correct length.
How's that work? '39 speedometer has female threads while the speedometer end of a Mustang cable has male threads.
Rich B has it correct. The 39 speedo has female threads. If you bought a speedo cable on e-Bay for a C-4 one end will work for the transmission end, but will not work for the '39 speedo end.I can get a picture next weekend when I take the 39 truck 60mph speedometer out and put in a 39 deluxe 100mph speedometer. The C4 speedometer cable I got off eBay.

That is correct I made a mistake. I got a 39 pickup truck cable and it fitted the C4 bullet
