While removing the rotted out passenger door on my 93 I ended up snapping off 3 of the 4 bolts (2 were completely missing!) on the hinge to body bolts. I am having a hell of a time drilling these out without completely destroying the backing plate, plus the bottom one pictured below is pretty well rusted. Does a replacement for this exist or am I better off taking the plate to a machinist to see if they could replicate it for me out of fresh stock?
