is there any helical cut LAYGEARS available in 4sync
other than 22G1040 or 22G927
they both have the same teeth 15-20-25-29
are there any pre A+ gears with an overdrive?
other than changing the diff or drop gears?

don't think so, doesn't seem like something BMC would have done... are there even any A+ gears with an overdrive?

They are all 1:1 in top gear unless you go for a 5 speed box.
And some of those have a torque limit- their 5th ain't that strong.

For those wanting more detail on the developmental changes made to the Mini gearbox up to 1965 the following article from the late 1965 issue of BMC's Partner Magazine might be of interest.
