Seat swap, type 44

[Dave C]

Thanks Huw, and to everyone else who replied with suggestions and
encouragement.  It is much more complicated than I had expected, partly
(mainly?) because the old seats are heated and the new ones are not, plus
being next generation.  Bentley actually has separate sections for heated vs
non-heated.  Anyway, due to Holiday and other idstractions I decided to set
this project aside and haven't completed it yet.  Whenever I get around to
finding a solution I'll post again with the results.
Thanks,
Dave C.
