[C320-list] Press Stud for Cockpit Cushions

[Annie Bennett]

Many thanks to all who replied on this.  I don't have many tools so called a shipwright for help.  It turned out I was lucky.  I'd thought the base of the screw was still stuck in the seat - partly because what broke off was so short.  The shipwright said the factory had cut the screw off a bit too short.  His replacement stud was slightly thicker than the original and he cut it off longer so he was able to use the same hole.  Annie 1073
