C3 Alloy Wheel Bolts WARNING

[CitTone]

If you are unfortunate enough to snap the ends off the security bolts on your C3 original alloys, DON'T buy Grayston LB127s, for example from PR Motorsport.
These are advertised by PR as being suitable for Xsara, Picasso, C5, C3, and Berlingo, but Grayston themselves state that they are for cars UP TO year 2000.
Although they have the necessary flat spacer washer, they do NOT have the stepped shank and taper of the original bolts, and would therefore not clamp the wheel correctly.

I bought some, and PR seem unwilling to answer any emails I have sent (3 so far) on the subject.
