After much unsuccessful searching, we finally made the decision to cut the original fender for a spare tire mount. It was actually for the best as the original cutout was actually a bit too small for the size tire that's on the truck.
We were able to make a pattern off of an original fender with a spare cutout to at least get us close and make it look like it came from the factory.
I was almost a bit hesitate to start cutting...almost...but once I got a whiff of that nice shiny paint burning, all was good.
