Can anybody tell me where i can buy plastic clip nuts from so i can fit my mudflaps.I don't want to use the metal ones as they will scratch the finished paintwork on wings.

 

Skid mate,
Go to focus diy and look for rawplugs they do a rubber bung fixing with a nut within the rubber as you tighten the bolt its about 10mm it compresses the rubber I used them on my flaps good solid job and does not damage the paintwork.
