I've bought a pair to fit to my 4/4. Just trying to find out how to wire them up before i take the plunge and start drilling! Rumour has it that the wiring is still there tucked up under the wing somewhere!
I got mine at the Race Retro show earlier this year from this place.
stafford vehicle wiring They do a wide range, mine are made of chromed brass and lovely quality and as per the Lucas ones fitted to Morgans. The owner said he supplied Morgan from time to time.
There was a 4 seater in the factory last week in bare metal with the front wings drilled for the sidelights...so you must still be able to request them.
