The central dent you have outlined in the photo is not evident in my unused NOS rear guard. It was quite common to see this dent in standard and touring guards in 'the poor maintenance' 60s and was caused by the Vincent damper leaking all its oil away and so loosing its hydraulic bump stop. This on full suspension bump bent F28/2, the rear mounting bolt/stud, allowing the bottom of the damper to clout the mudguardThanks Ian, Good to know. Thanks for not banishing me.
The dent shown in Davidd's last photo looks more pronounced than mine, but this fender is not original to the bike and hasn't been fitted yet. It may require some more persuasion. My front fender doesn't have any dents (other than the indents to clear the forks)and it looks as though the stays will fit without any.
I haven't fitted a front tyre yet, so not sure about clearance without dents for the stays.
