1975 A833 od, any useful parts for non od boxes

The two o/d gears , IIRC are 18tooth and 20 tooth.I have examples of both. The 18 toother shatters with just the tiniest too much input, you have to be very gentle with it.

Is this maybe backwards? Based on the below, the .73 OD uses the 18 tooth gear, but it almost seems like you prefer the .73 OD. Am I misunderstanding?

the calculated ratios are 3.088-1.67-1.00-.73od

..........and the ratios are 3.088-1.67-1.00-.71od

How about the output size? Any relation between the gears and size of the output? Pretty sure mine is a 727 size output, and seems like it came out of a '76 Feather Duster. I know it is an all aluminum case, too.

Lastly, here is a link to some old info I posted some time ago about swapping OD parts into a non-OD case. Just some more info. Old Hot Rod Article about converting a std 4 speed to OD
