How to install a Stewart Warner Speedometer?

[fas141]

I created a custom gauge package for my Monza. All Stewart Warner gauges and it looks great. Problem is the factory Monza speedometer cable does not attach to the SW speedometer. Does anyone know how to go about getting it to attach/work? I thought maybe there would be an adapter but I could not find anything. Thanks for help.

Does the S-W speedo use a threaded connection? You could find a universal cable with a length close enough and the threaded nut. Or if the speedo is in the same location in the dash, there should be enough tension on the cable casing were you may be able to just link it up, and not worry about a solid connection.

I had a problem with my factory speedo in the El Camino. The factory connection uses the threaded nut, and when I had it tight the inner cable was a bit too long and made the speedo go crazy. I shortened up the inner cable a bit and didn't tighten the nut, it works fine now.

Thanks, I was hoping there was some sort of adapter but maybe just finding a different cable might be the way to go. The SW has a threaded output on it.

Well, thought I would add this.. I also love Mopars.. so... a speedometer cable from a 67 Coronet not only fit the 4-speed end in the Monza but the SW speedo.. AND.. the length was perfect and the Mopar grommet fit the firewall on the Monza. I could not believe it.. lol..
