Wasn't the Riley 1.5 or Wolsely 1500 the highest ratio that would fit the Midget axle? probably rarer than rocking horse manure though

The late (post 1978) Midgets use a 3.7:1 diff, but these seem to be hard to find. As for something lower, i dont believe they made any.

It is an A series axle

Diff was used in quite a few cars (some of which had B series engines) lots of short ratios were made for A35 vans and the like but as it was only used in cars up to 1600cc you will be pushed to find a longer ratio than 3.77.

Usual way round it is to fit a type 9 gearbox.

This this the same axle as the Marina/Ital used? What ratio did the 1800 versions use?

Marina/Ital was a Triumph Toledo/Dolomite axle modified for leaf springs. Different whel PCD

MGB (except for the first year or twos of B production) was a much heavier Salsbury unit
