Apart from the 166 it is true that all the TS sumps are interchangeable (although the warning about dipsticks above applies) - the 155 sumps are the ones with additional tappings for oil level and temp sensors.
Changing the sump isn't too hard - but a bit fiddly. You need some long ribe bits for the bolts at the clutch end - they are pretty awkward to get at. There is also an awkward 13mm bolt through the driveshaft support that can be a pain. Once the bolts are all out, the sump will still be stuck on with the sealant - I normally run a Stanley knife (box-cutter) along the joint to remove as much of the sealant as possible - then its a question of tapping a thin chisel or some such into the joint to start to split the joint. Once its seperate, you'll need to remove one of the 11mm bolts that hold the oil pick-up pipe to the block, and loosen the other, to allow it to swivel so that the sump can be juggled off. Be careful when you replace this to make sure that the gasket is correctly located and not blocking the pick-up.....
I've a few sumps if you get stuck.
