Who says?The tooth angles will not match up.
Has anybody done this before?You could potentially run G50 with a different custom made ring and pinion
What makes you think that?I don't think there is room inside the case to flip.
For ****s sake, if the pinion is 16mm below the CW centerline then it cannot be flipped- period. & even if you get a reverse cut crownwheel & pinion set made the crownwheel would have to be reduced in dia to clear the casting relief area around the input shaft seal & clutch release fork.
