Update:
Stainless steel bumpers now fitted and they look fabulous
. They arrived really quickly and with no additional nonsense from HM Customs. There were no additional unneeded holes in mine which, given some previous posts I was expecting so at least I don't have to worry about covering them.
The bolt positions for the front bumper brackets were a bit off kilter which made it a bit tricky to fit but easily overcome with a bit of gentle persuasion. They were quite tight to both wings so I had to be really careful not to scratch my new paintwork. I need to figure out a way to bolt the 2 ends steady as the holes in the wings and brackets didn't line up but they don't flap around so I not too worried at the mo. Rear bumper fitted fine.
If I could work out how to attach photos I would.
