Mark,
Wasn't implying that there is an electric shifter for your axle, just what to look for and where I'd start if there really is such a thing.
And by the sounds of it there may not be one.
My diesel project is really slow, haven't done anything in months, to much other stuff to do and not much money left after the morgage...
Feel like I really need to get it done soon though, more and more lately I miss not having a truck of my own.
