Wanted F355 Berlinetta Driver's Seatback

Looking for a Driver's seatback for a LHD Berlinetta (I believe that a GTS seat would also work), with both the Lumbar Support and Bolster Width adjustment fully functional. Color and leather condition don't really matter, but the lumbar and width adjustments must work, and the foam cushioning inside, in good condition. Will even get the whole seat if absolutely necessary.
Headrest isn't needed, nor is the center pad - these have already been recovered.

Those from the Spider are very different, and unusable.

Details on the issue are covered in this thread, started by another user almost 7 years ago, with no solution then, either: Lumbar Support Adjustment

 

Late weekend bump to start the new week.
