Jack, I followed the thread after your first post and am very sorry to hear of this outcome. We were all hoping for a much happier ending.
Two years ago I did quite serious front end damage to my TR4a in a racing accident, and since there was no insurance on track events I faced some tough financial decisions.
The early quotes started at $10,000 and I had reason to believe I would be asked for more when the job was underway and it was too late to back out, as additional, hidden damage was sure to surface as the car was disassembled.
I eventually decided to purchase a donor car from a desert state, and do as much of the work myself as possible to keep costs down. After selling off duplicate and unneeded parts and p[aying for professional painting and chassis repairs I have spent about $13,000, but will end up with a very nice restored car,completely rust free, and much better than the car I started with.
My car is not unit construction like yours, and the damage was different, but I hope my success may inspire you to buy back the car and use your settlement to restore it. It would be a shame to lose another of these fine cars.
Good Luck!
Simon.
