The late engine flywheel may not be drilled for the smaller clutch, so use the larger clutch, but note that the clutch cover (pressure plate) is different from the S3 for the 2a, having a spacer on the release fingers. Just a matter of buying the right part, and you probably want to replace it (and the driven plate) anyway while the engine is out.
    John sometimes I can be a bit thick but would I be correct in assuming from your post a 9.5" clutch plate will fit behind a three finger type 9" pressure plate with top hat type release bearing........asking because I've inherited from PO's several new 9.5" clutch plates but no 9" if I can use them on my 2a it would be good

    No. The 9" clutch has the three finger clutch cover with coil springs, the 9.5" has a diaphragm type clutch cover with lots of fingers that is similar to the S3 one, except that it has a spacer ring over the fingers to match the S2a withdrawal sleeve. But your old S2a flywheel should be drilled for both types, although the S3 flywheel may only be drilled for the larger one.

    I hope that is clearer!

    I think if you are putting in a Landrover engine - use the Landrover flywheel! And the 9.5" clutch is preferable as well!
