I have come across a pair of Recaro seats. They are of this configuration:

Except that mine have adjustment knobs instead of the "turnbuckle" and the center section is vinyl. I am trying to figure out if they are production seats or period aftermarket option. The rails appear to be the same as those fitted to the 911's based on my forum search. What other cars would have been fitted with these seats?

Regards,
