I snagged a pair of inside door latchs out of a '98 Corolla to replace the bulky door handls/lock mechanism that came in the Jeep. I don't figure I'll need locks any more with these doors.
I traced out the footprint of the door latch and cut it into my diamondplate. I then took the rod from the old handle, cut it off and bent it to fit into the Corolla handle. It took me a couple times bending it to get it right but it works pretty slick.
I haven't got the door panels finished yet but I have them cut out. I plan to fold the vinyl around the cardboard and re-attach it to the door. It should look pretty good.
