Hi John, yes that’s mine – vin 143961 a Dorchester 3.6Man as you know..
Well that has to be the definitive answer then, I’m sure you would have come across build sheets during your research too if they had been factory fit.

I’d be interested in any pics of the Lady Diana car rear seats too if anyone has some, as the only rear seat conversions I have seen are similar to mine being coupe spec. rear seat and squab which are a direct fit once the rear plywood cupboards are removed.

The woodsmoke user ID was just what I used for another forum, maybe I should change it back to a more normal name format..

Sorry Laurence if I doubted your knowledge!
