Actually I take back what I said, I have just double checked, and you are correct! The LT77S driven gear I have is a 21 tooth with straight cut teeth. the gear in my R5-150 is a 23 tooth black, with helical cut gears (and bigger diameter)
I need a 22 tooth gear, presumably for an LT77. Anyone know what the correct part number is for this?

remember it's only a bodge if it DOSN'T worK
I have the black one at the moment, but thanks anyway. Just drove the van for about 200kms today, first trip since changing the diff ratio. Speedo reads perfect, but odometer is about 5% under reading. I think I will just live with that. I seem to remember something Chris posted about the auto one, being hard to get etc.
Just to remind people - Jaycar do a speedo corrector. Only for electronic types. Takes in the pulses from the sensor and multiplies or divides them to your requirements, and sends them to the head. Costs about £20 as a kit, and easy to make as these things go.
Great if you change the axle ratio, etc, or can't get the correct gearbox sensor, or want to use a non standard head.
If anyone fancies one but can't build electronics, get in touch - I usually have one 'in stock'. Costs £50 in a nice enclosure.
