Thank you again Matt. I managed to get it through the MOT with the temp. seat belt on the drivers side, so the urgency has receded! But must get it sorted for next spring, I have decided to SORN her for the winter months.
Changing the subject, have you considered showing your car at 'classics on the common' at Harpenden? You aren't too far away at Amersham, I plan to do it again next year, be great to be able to compare notes (and cars).
