New seals obtained from sussexclassiccar. These seals go under the windscreen, where it bolts to the body. Problem being, these seals are new and don't compress, so I couldn't fit any of the 4 bolts that hold the screen on.
Struggled for ages, then gave up. I cut some rubber matting to the right shape and fitted the screen without problem.
The number plate plate lamp was next. I had fitted the plinth some time ago. As usual this had to be removed to fit the light. Then the new light unit has M5 studs not 3/16". Another trip to the shops for some nuts to fit. With the wires soldered and the earth bolted to the boot lock support, it should work if I ever get to fit a battery.
