Identify this diff ratio?

Postby mollythemoggie » Sat Feb 16, 2019 11:37 pm

Hi I was just wondering the best way to identify what ratio a diff is I have.. It has the numbers aya7010 stamped on the saddle things with 126 on one of them and 109 on the other

Thanks very much!

Are you sure it is a Morris Diff? Looks like cast iron and the "AYA" code is unusual.

May be Morris but not a Minor one.

ATA7034 on the main bearing caps, normally, isn't it?

Also note the position of the diff ratio 9/38 on the diff nose in the link above.

Some AYA codes on the 1800 Landcrab, if that helps. I don't know much about RWD Austins of that period.
