I'm sure this has been asked (and answered) before, but I couldn't find a definitive answer on the forum in my searches. I am no expert on oils, so please bear with me.

I'd like to change the oil in the M41 gearbox and rear differential in my '68 Amazon. Driving in the UK all year round, so mostly around 10 deg C.

The green book states
gearbox (non overdrive): SAE 80 all year round "hypoid oil must not be used"
final drive: SAE 90

Can anyone recommend which oil to purchase for gearbox and final drive please? What are the best brands to get? Is there much of a difference between the more expensive vs the cheaper alternatives?
Many thanks for your advice.
