OK, Saturday I picked up my daughter from a 5 month school in Holbæk and in the evening I got some wood, thick metal and a since I don't have a bottle jack I used a scissor jack and then made the necessary arrangements. Wood frame at the back of the door opening, wood bracing to the rear inner wheel well, metal piece welded to a patch on the floor, metal holder for the front door corner and wood shaped to the front corner.
A few turns on the jack, a bit of creaking from the body and it was about half way there. A bit more violence, more turns on the jack and the door opening measures exactly what the other side measures. A test of the door and everything is fine. The windshield posts are also now exactly parallel as viewed from the side.
I was to a retirement party at the office Friday and a guy said he woud give me some wheels for a Mini. I was so happy with the door frame result that Sunday I went out and got the wheels and tires. He still wanted money for them, but they were cheap enough. They are Bridgestone tires on "GB" wheels (BWA Racing)
Peter has also found an Allegro 1275 A+ engine and gearbox for cheap. I am wondering about the wisdom of using this. Worse mileage and the cost of converting to disk brakes.
I currently have a 998 and a 1098 both of which need rebuilding, a 22G1832 box and several 12G295 heads, all of which are standard overall thickness and drum brakes.
