Thanks for your comments, highly appreciated.
All of you are perfectly right and if OEM parts are available to rechrome or even NOS parts. I'm not certain if my bumpers are OEM or have been replaced to NOS in a certain moment of time.
Re-chroming in Germany will be very difficult.
1. price which is about your range, but in €.
2. companies are refusing to rechrome such big parts
However, if to consider a repro part, which manufacturer/supplier would fit best, best as possible?
Thank you and a "Happy New Year".
