I checked the screw size and pitch (10-23 and M5x0.9 are very close is size). I used a 10-32 tap to
thread the 2 mounting holes on each bracket. I didn't worry about the 2 screws that hold the oven door because they are self-tapping screws. The assembly went smoothly after that. The oven door closure is back to the original.
