The mounting holes for brake assembly # AKEBRK-35L are indeed 4 inches diagonally from the center of one to the center of the other. Side to side or top to bottom the holes are spaced approximately 2-7/8 inches apart on center. The pilot hole is approximately 3 inches. You are correct, those are fairly standard.

The matching right assembly is # AKEBRK-35R.
