Thanks i'll try Ozdat but this thread was a great read and very informative the 4 speed is the way to go for me . Cheers

Hi i was wondering which year and car the l4n71b came to australia and would it fit the l20b. Cheers

Thanks mate for your input i can get a humber hawk diff with the correct ratio and PCD to suit my commer and front disc conversion as well, Now only have to find the 4 speed auto.. Cheers

So if i change to a 4.2:1 diff ratio would it benefit me to also change to the 4 speed auto?

yes it is the British one

how can u tell which box it is, british or us?

Hi, I've got a l20b mated to a BW35 auto and a diff ratio of 2.8:1 with 205 65r 15 tyres in a 62 Commer van which was in the car when i got it, I'm still restoring the van but have some questions regarding this set up. 1/ Would anyone know if this set up would work. 2/ Is there a 4 speed auto to fit the l20b to give it longer legs when cruising 3/ i'm thinking 2.8;1 is not right for this set up maybe 4.2:1 ? Any help would be gratefull
