2a box into a Series 3

Im in the process of fitting a Series 2A gearbox into my Series 3. (the old box selectors has broke so needs stripping down and servicing).

Is this a case of swopping the bell housings over and away we go? I noticed that the main shaft on the 2A has a screw type grove on it, just before the clutch teeth. The Series 3 shaft didnt have this, i am assuming this will not be a problem as i think it was to allow the oil to flow (the series 3 bell housing now has the oil seal lower down) but am just checking before fitting everything back together. I could take some pictures if required but this wont be till the weekend.

aye yule be fine the 2a box is said to be the stronger of the two

Cheers for the very quick reply. I didnt think it would be a problem. The different clutch's wont make a difference i hope because this is controlled within the bell housing, which i am swopping.
I can't find any information about this, and i thought it would be a fairly common subject.....

would it not be easier to just change yer clutch slave?

I would have said the same, changing the clutch slave would only mean sourcing the slave bracket if one never came with your 2a box,the linkages and a little bit of pipework!
