Extra long speedo or tach cable?

[patracy]

Does anyone know of a NSN for a very long speedo or tach cable? Maybe something from like a M977 or something? I was going to go with a GPS speedo for a project. But if I can get a cable cheaper, I have a spare speedo laying around.

Maybe you can make a coupler? something that can attach 2 cables together?

Cable ends are different.

I assume you found your cable by now. If so what did you find?

Has anyone heard of a company making custom lengths?

I need one for the V100. Haven't measured yet. Found a 140" Dodge van cable on ebay. Probably too short. Seen 6' extensions on ebay too. Looks like threads are 5/8 x 18 on military gauges and 7/8 x 18 trans, my NPG542 anyways. Pretty std in auto industry.
