First on the agenda were effective repairs to the rotten base unit.
From the picture you can see the blue areas indicate repairs to the base unit, the green areas indicate additional strengthening, and the red areas were removed ! There were also repairs to the underside.

This type of work is quite straight forward on the P6 as all the exterior body panels can be unbolted, allowing easy access to the base unit. It also helps as most repairs won't be visible externally so the emphasis can be placed on structural strength not just good looking repairs.
One fun moment came as we were air-sawing through the roof section just behind the windscreen surround, only to find that the whole panel unbolted, as we intended to use the roof as a hardtop, we quickly welded over the cut before unbolting the panel.

Then came the moment of truth as we ground through the rear pillers and door posts. Having seen people cut roofs off morris minors without extra strength, and the resulting fold up when you first open the doors, we were pleased to see no movement in the chassis. Even jacking one corner off the ground still left the doors able to open and close easilly. Eight years on it has only moved a couple of millimeters at most, so we are very pleased with the work. The picture shows the original sill section and our finished sill section, with the addition steel shown in blue, all the extra width did cause problems with re-fitting the seats later.

After the base unit came the bodywork. Athough the wings were all in very good condition, the doors unfortunately were not. As with most cars, the door bottoms were rotting heavily, although the outer skins weren't too bad. So we cut large sections from the inside door bottoms and some smaller sections from the outer skins. We replaced the inner sections with steel leaving large gaps for effective drainage. We also removed the outer door handles and patched over the holes, filling them flat. We decided to leave the rear doors opening as this would aid maintenance, even though we had welded large steel sections across the openings.
