Not quite sure what you're asking, but 9:38 IS 4.22, if that's it

So 10/39 is 3.9:1 diff!

It wasn't, to the Mog, anyway. Somebody's bound to know which cars had them, as lots of BMC cars had the same type of diff.

At a guess, Wolseley 1500 perhaps? That 3.7:1 diff from a Riley 1.5 that I posted about a few days ago sold for £81.

The 1275cc midgets had the 3.9-1 diff ratio.

Dunno really - look for any 'blueing' - and lack of wear marks on the splines!

There was no blueing on my hardened shafts but the splines were 'as
new'.

Yes its a Midget diff as both the Wolseley and Riley had the 3.7 or 11/41 as confirmed by the 1500 owners club spares person and plastic orange.

Most of the 1500 midgets have the 3.9 too ;) although the last 3/4 years of prioduction used the 3.7
