if you need to fit it, make sure you get every little screw and bit of trim and ecu bracket, the works
there is just enough give in the looms to move everythign about as you gain the passenger cubby hole if oyu do it right, i was never a fan of puttin gthe ecu's there as they were a right pain in the arse to get out, but with the glovebox out they are much easier
also need to use the later a piller trims and plastic kick panels in the footwells and you'll lose the speakers in the lwoer dash
as for the column, the later ones are adjustable, and it's simply a case of removeing the new column and putting it into the 3 door
the only place you are going ot have issues is with the stalks for the washers/wipers as the 3 doors have buttons on the dash whereas the rest of the cars have them in the column stalks
you can still fit the centre door opening and lights out stuff into the later dash with a bit of fiddling
you also need to use the later spec heater controls, them 3 screws just need to come out and everythign comes out with it, just unclip it form the heater box and job done
one more thing, the surround is clipped in on the left of the heater vents, so you need to be very careful pulling it out as once it's broken it's going to need a bit of fixing to stop it from rattling like a kid with a new rattle when you are driving along
it's an easy job when you've got a donor car to strip the bits from
