No I didnt notice the missing headlamps Phil. The gearbox and axle should be fine unless you are very unlucky. The engine might just want freeing off. When I got hold of my old one it had sat in a field for many years. We just drained the water and gunk out of the gearbox and axle, took the head off and decoked it and it ran fine. The only money spent on the engine was a new head gasket, spark plugs and an Jolley kit for the dizzy. As for the electrics, voltage reg etc, they come up regularly on ebay and are fairly generic.
