Did you just buy your own sheet of aluminum and make your own armor so the cutout matches the handle?
Yes, I just bought a sheet of Aluminum that I could cut two door skins out of. Cut the holes for the door latches. Works.
I also welded an arm rest out of square tube to the inner door frame. I'll post a pic in a sec. I'd tell you the rest of my plan, but then I'd have to kill you.
