Looking to change the backbox without garage prices is it kind of easy?cheerz dan

Very easy, did mine on the side of the road, it's held on by 2 bolts a 3 rubber hangers, it you jack the car up on the n/s or park the n/s side on the kurb it gives you enough room to get under :thumb:

as granby says, nice and easy:)

couple of tips (not sure how old your car is) you might need a new gasket, it's a right pain in the arse if you take it apart and the thing is knackered, they're only about a fiver anyway.
and it's worth spraying a bit of wd40 on the nuts over a couple of days.
i also put a little on the rubber hangers as they can be a bit of a git to unhook if you're in limited space.
