Early GT Seats?

[jaudette3]

I found a pair of these over the weekend. The owner, who is does reupholstery of (very) high level cars, says they are from a vintage Porsche GT. They're wider than Speedster seats and are the same width as 356 T6's and early 911's. They have their original upholstery on them. Can anyone identity them?

Thanks,
John Audette

P.S. I posted this at Early 911S Registry also.
