hey mate you could try james madden at the off road shop ,he plays around with the un5`s he uses a mechanical set up, which I copied on mine when I had one, my mate used corolla cables on his, ill let you now if he still has them sitting around
A lot of guys use a cable shifter. I think mine was out of a magna and it works great with the kombi box but I know others use same set up with Reno box just modify or make something to work the linkages on the gearbox.
hey mate,,i thought i still had the whole set up ,but i only have the cables,they are out of a mid 90s corolla,worked great,a fella in wa bought my mates un5 ,my broken box was with that and all the brackets,was pretty easy to set up,,
