What would be the gear ratios in a 1990 Rover mini Cooper, rod change box. (I believe the diff ratio is 3.1:1).

Still searching for gear set ratios. I found this website http://www.calverst.com/articles/Gearbo ... _types.htm dose the list of ratios half way down match what's avaliable in ozzy minis?

My gearbox ratios are the same as the 4 sync 850/998/1098 list.
My casing is a 22G1832 & layshaft P/no is 22G297, with 31 26 21 17 tooth count. I'm pretty sure the gearbox came of a 998 originally too.
Using my link above and knowing the above info plus the drop gears, that's what I came up with! It did help having the gearbox apart at the time.

Cheers Shane
