Retro fitting a combination of BMW and aftermarket PDC

[X-ray Lima]

So, I've been informed by an installation company that aftermarket PDC cannot be fitted to my 'non factory PDC'd' E53 due to the massive crash bar behind the flat (coloured) part of the bumper.

I've contacted a local parts supplier and the two parts of the PDC mounts for the E53 can still be purchased.

My question is, can the PDC mounts be fitted up to the standard bar, or are the two bars inherently different behind the scenes??

I realise this will mean I need to find an aftermarket kit where the PDC sensors are of a suitable diameter to fit the BMW mounts, but I am sure something can be organised......

Anyway, main question is.... will I be able to fit the mounts to the standard bar??

Thanks in advance......
