Do you have any junkyards near by? I'd start there. Or find a friend with one, or some random person at the offroad grounds, and take a hands on look at the linkage, shift box that's cut into the floor, shifter, and plastic shroud to hide it all.
Once you know exactly what is needed, I'm sure we can pull our spare parts together to finish off your setup. I know I have an extra support rod (from a 700r4 bell housing to 208) and extra linkage from the shifter to tranny input.
Otherwise, I don't know any parts lists for the shifter setup.
