it looks as though all 89-95 minis have that rectangular recessed area in the middle of the t/gate......LOOKIN FOR A GATE THAT WAS flat but looks like it has to be made....
Buy a tailgate skin from Grant Kustoms. You remove the stock skin by drilling out spot welds and prying it off, and the new one goes on pretty much the same with a little welding.
ya just order a tailgate skin from grant kustoms. are you trying to keep your tailgate? if not just buy a full skin. they look real good. and then you can get rid of the recessed area
like everybody else said, you will need to get a tailgate skin. they are alot easier to install than a cal combo.
