Not sure if this has been posted before, but I could not find it on Moparts or anywhere else and had to figure this one out myself. If you happen to need a retrofit speedometer cable for an early 1962-1965 B-Body using 1966 and later 727 Torqueflite, I found a perfect part that fits. Hold on to your chairs, it is for a '67-'68 CAMARO!!!
The original speedometer cable for my 1964 Plymouth Savoy with the pushbutton 727 measures 68 1/2 inches. I found that the 1967-68 Camaro originally uses a 69 inch Speedometer Cable Assembly. I ordered one on eBay, and installed it yesterday. It fits perfect and fits the 727 and speedometer like a glove. FYI...I tried the local Napa, Autozone, Oreilly's, ect, also, and none had a cable even close to the right length, so back to the internet for parts. This might save you some time, try these links:
Part numbers on the speedometer cable is SC-72 and W-871.
