Clutch housing cover

[App K]

I have two covers looking identical in every way as far as I can see;
Both have different part numbers for some reason.
22G 271
22A 109
Can any of you chaps cross reference these for me?
Cheers

From memory - the A is the common one and the G the cooper one, but most parts lists show them as interchangeable.

Visually, people look for the starter motor housing which has a squared off end on earlier cars - but not sure of the change point?

Thanks for that Andy.
Both of these have the same starter motor housings, both identical.
I know the flywheel housings differ considerably from year to year but seemingly the clutch housing cover doesn’t...just the part number, which is a bit strange.

The housing on my 65 S is 22G271 with the flat starter nose.
