series gearbox woes ( again)

Yes and no. The clutch plate & release mechanisim is different between the two. The fixing holes for the bellhousing are in the same place, so it will bolt on. Ideally you're going to need a S3 flywheel, clutch plate, pressure plate, release bearing and the gearbox. I don't know wether a S3 pressure plate has the same fixing holes as a S2, although the diameter of the plate is different so they may well be. As you're using a differnt engine, you may need to drill/tap new mounting holes in your flywheel for the S3 pressure plate, it depends on how it was fitted in the first place, I suppose. The only thing you definitly will need to change is the clutch hose/piping as the slave cylinder is on the opposite side of the gearbox.

A bit more difficult than changing a gearbox, but a simple swap is always simpler, and less trouble

The transfer box has nothing to do with the clutch or bellhousing. I can't answer Alex's question but Alex can safely ignore Andy's posting as somewhere a couple of wires seem to have got crossed.
