In Search of Etype FHC seats

I’m looking for a pair of Etype 3.8 FHC seats that would be correct for a 63-64 coupe. Conditon is not that important as they will be restored. Any help is appreciated.

Here is a set on the Dallas marketplace for a 65. I don’t personally know how they may differ from 63/64.

65 seats

The early coupes, up to sometime in 1963, had what was sometimes referred to as the narrow backed “roadster seats.”
