arch mounting. nylon threads?

[NorwegianGTE]

I've struggled to mount one of my rear arches properly as some bolts were missing.
I've learned that the bolts and nuts are no longer made.

I've read that nylon threads and nuts is the most popular fix. by glueing bolt on the arch. wouldn't this make it extremely fragile? as the original bolts are screwed into the arch I would suppose that the arch could fall of easily if you were to drive at a bumpy road etc.

I suppose you could try and bond some threaded bar into the arch, with fibreglass resin or something similar. And then line it up with the body work and then spin some nuts ono it  under the arch.

I wouldn't use nylock nuts, they need a decent amount of force and you might break the threaded bar off again.

It's unlikely the rear arch will just fall off. You can put some rivets on the sections that are hidden out of sight. Underneath the rear light and along the sill for example.
