[Healeys] Overdrive question

[simon.lachlan at alexarevel.plus.com]

I did the same with my BT7.

I didn't count the teeth in the car but remain content that all the teeth in
my skull are originals. No repros and little ironwork.

Sorry, couldn't resist.

I put a 28% and a 3.54 diff in the BJ8. The overdrive sun and planet gears
are the only difference and they are interchangeable in sets between the 22%
and the 28%

The 22% overdrive has 24 teeth on the large planet, 15 teeth on the small
planet, and 21 teeth on the sun gear

The 28% overdrive has 21 teeth on the large planet, 15 teeth on the small
planet, and a 24 tooth sun gear.

Both use a 60 tooth annulus.
