hey i was wondering what gear ratio's this arb unit is good for. its going in a dana 60. the arb makes the two units one for 410 and down one 456 and up part numbers rd21 and rd22. well he doesnt know which number it is but it does have these numbers on the unit. where the ring gear bolts there is number 0305 23k5 then on the side of the unit is stamped 9704121 and on the back of where the ring gear is he said it is stamped 02-11. thanks for any help leading to the answer of what gear ratio, thanks, scott
