Default 58 Vette with LS6/T56 - How do I get the speedo to function?

Hi Guys,

I've fitted an LS6 engine and a T56 transmission into my 1958 Corvette. I want to keep the original look of the speedo, so how do I convert electronic to mechanical? I'm told there are 3 options:
1. fit an "x box" which converts the electronic impulse to a mecanical cable. Don't know anything about this though.
2. Relocate the VSS to the other side of the transmission housing and install a mechanical gear drive where the VSS came from.
3. Adapt electronic speedo internals to my original speedo housing.

What is the best solution? Does anyone know who can do the machining for option 2? Thanks

Any of your options will work, number 1 is probably the easiest.

Thanks John. I had heard about the x box but didn't know where to get one.

We bought a kit from www.jagsthatrun.com, it wasnt exactly easy, we had a $350 machine shop bill, plus the roughly $200 it cost for the kit. I am happy that my factory 69 Camaro speedo works though <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

This sounds like you have kept a mechanical speedo. So what did the kit have in it and what machining was involved? Are you satisfied with how your speedo now works?

I've got the Cable-X and it works great! Especially if you do a gear change....you can recalibrate the speedo yourself with the flip of a few dipswitches!
