You can fit all the old MK2 1.8 bits on the MK3 lump if you like, but ideally just keep all the MK3 bits. The PAS pump brackets in particular are much better on the MK3. Oh and to do this you need to fit the MK3 2e front water flange, as the hoses are different. This has a takeoff for the header tank, so you block off the old one on the rad by screwing a bolt into the old pipe and jubileeing it.
You simply pull the old head off and fit your MK2 head, and everything plugs in

With a bit more effort you can go all the way like this, breathers need work though:

For £100 it better be complete tbh, I got mine for £40 which included pretty much everything, all anxileries, head, inlet etc
