Speedometer cable length with 4 speed transmission

[loneagle]

I'm running a Super t-10 4 speed transmission with the speedo drive located on the passanger side. I'm trying to figure out what length cable I need?

I have a choice between 100" or 120"ers. I measured my stocker and it's 84" but for the drivers side. I'm not sure if the 100" will be long enough. :?

I'd imagine you could run it over top of the trans to the passenger side, that should give you a little more length to route it.

OK, Thanks! I've got a 100 incher that I'm going to try. Hopefully it'll do the trick!

If you havn't removed the original speedo cable yet tie a string to the end before you pull it out through the firewall so you can pull the new one back through. They are not that easy to slide through the dash if you have everything in place without a string attached to it to guide the cable
