    Does anyone know the spec and a supplier of the chrome dome head bolts that fasten the front fibreglass wings to the stays? Preferably on an early Cabrio Having a hard time finding something that seems to be the same measurements as on the car!

    thanks,

    Thanks Steve, I have their web site open at the moment, no head width measurements so I'll have to give them a call.

    This seems close, nice wide flat dome.

    Always best, if you are local, it’s a veritable Aladdin’s cave, if the let you back stage. I was lucky, knew the owners and my staff were in there almost daily,
    If they did not have what I wanted off the shelf, they would find a valid alternative, even from another supplier.

    Thats the type that I would choose as the square shank prevents the bolt turning and the plain flat chromed head looks the part.

    I never liked the way the wings where retained, so when I built my Berlinetta I bonded a length of angle to the underside (see photo) and bolted that to the supplied mounting bracket.
    I believed this produced a better look to the wings, no problems with rusting chrome bolts.
    Over 30 years I've had no problems with wing security.
    Down to personal preferences.
    Probably a job that should be carried out when building the car, or before a re-spray.

    That’s a very sensible and smart way of doing it Dave.

    As we needed towing mirrors on the car at times the holes may be larger than standard
    regards Liz

    Thanks Liz, yes they are, I'm going to go for a bolt with a larger head if I can find one. If not then I'll fill/re-make with fibreglass and drill again. Nice little job over the winter.
