They can be interchanged but are not the same internally

The gear ratios are different.
The overall dimensions are the same so the gearbox will fit. The clutch release arm will have to be changed as the Sprite/MG has a hydraulic release mechanism.
See chart below for part number comparisons

I enjoy the closer ratios of a smooth case Spridget box with a 948 and 4.55. You may find the same with a 1098 and a 4.22. The gap between 2nd and 3rd is much reduced. The Minor 1st is usually too low anyway.

Sorry to butt in but I just want to say that I am absolutely staggered by the amount of knowledge/data that Phil has or is able to get hold of and share on here!
Is there anything he doesn't know?
