So the plot thickens a little....
Got the second hand silver bumper. Looks a good match. Has 4x parking sensors, 2 x fogs and grills. Reasonable condition with the odd wear and tear, but WAY better than mine and it's all in one piece too
WINNING.....well almost.....In the rush to buy I missed a semi-critical point. No headlight washers
The rear of the bumper seems to have the mountings, and I have the headlight washers on the original bumper and then I'm guessing it's cut a close to hole size, but a touch smaller with a dremmel and file to the correct size. The flip mechanism is all in the washer unit. Shouldn't be too bad. Maybe some touch up paint to dull the bumper black plastic around the holes?
Alternatively don't bother and delete the washers. Car has Bi-Xenons, is 2005 and having a look at the MOT gubbins, most the lega stuff is regarding cars later than 2009 - Obviously *IF* a car has something, it has to work, but a factory style delete would avoid even the question of if it has them!
