Hi Guy
Is this the kind of blackout headlamp you are looking for. If so try getting in touch with Brian Asbury. I think he had one on his table yesterday at the OMVA show.
As for the rear axel lamp I was talking with Eric Booth about what to use. He said the ones pictured below are correct.
This conversion would have been done in England. I picked up another of these lights yesterday (Brian Asbury) and the earlier style mount for it. I mounted it on the chassis crossmemer just above the rear diff. The angle of the mount allows the light to shine down onto the diff. I did have to drill two small 1/4" holes into the frame to bolt on the mount. As for wiring I added it to the "blackout" wiring with another 3 way connector.
I can post pictures of this but it wont be unitl next weekend.
I will post a picutre of how I mounted it next weekend.
