you'll also need to check what strut is fitted to the car, as the only tops you are likely to find these days will be for the last revision strut only. So a new strut may also be needed, and I believe the gaiter is also different to the early strut, just to add insult to injury! At least the leak-back hose will be the same
So works out around £4-500 per side from Cit, from memory (that's strut, top and gaiter), was 18+months ago that I was asking, so be seated before making that call
