Thanks for all the responses, I take the point about mount security but I've gone with this Wipac driving lamp bracket kit from Williams Morgan all the same.

My thinking is given these brackets are actually MMC made and are seen on so many Morgans they really can't be all bad, with the right closed cell sponge rubber bracket gaskets, large diameter backing washers and careful fitting I'm confident the setup can be made to work without vibration.

Ultimately I prefer the way the MMC brackets create a clean floating effect which will show off the beauty of my Marchal 670/680 fogs that I've fitted with the period correct Marchal yellow globe bulbs, sat behind the clear lenses these bulbs give a lovely subtle golden glow when the fogs are off.

The above look should work well on my bumperless and overider equiped Sport Green Plus 4, which I'm sympathetically back dating to give Monty the vintage club racer vibe.

Can anyone confirm if Morgan incorporated fog light wiring in the harness used on my 2012 Duratec Plus 4, or if I'll need to build a sub loom forward from the fog light relay?
