I will be putting a 302 & C-4 trans in my 49 ford. I have the stock speedo and wondering what to use for the speedo cable so the speedo works.
I have a 289/C4 in my 28 and a SW speedo, just bought a generic cable at Napa many years ago, works fine.
a cable for a 50s to early 60s ford should work fine. you'll need the correct gear and clip to go into the transmission. http://www.tciauto.com/tc/speedometer-gear-calculator/ shows Ford gears near the bottom of the page
cable like this might work... http://www.oreillyauto.com/site/c/detail/PIO0/CA3020/01175.oap? check the lenght, they have a longer one too
I had to have one made for my swap into a '56 Ford. A local Speedometer shop built one, no problem. Just take the two ends in and tell them how long.
I used a mid 60's Mustang c4 cable in my 49 Shoe , and Craig's (legend544) 50 shoebox as well. Fits like a glove , seriously !
