Recaro IS.N seats question, and spectrum fabric
 

I've acquired a pair of vintage Recaro seats with a label sticker that says "IS.N".
Are these a version of the LS seats?
They look like LS-C seats.
Any info will be helpful.

Also... anyone know where to find the orange spectrum Recaro fabric for when I have them reupholstered?

Not sure on model exactly, I'm sure the Recaro experts here will weigh in. A quick crosspost from a 2002 forum with some info:

Also, for the fabric: https://www.toughluck.jp/product/recaro-orange-spectrum

Thanks!

Here's a pic of the driver's seat. They are a set, in that they are specific to the side of the car. No adjustment or back release on the inside of the seats.

(Please forgive whomever upholstered these like this. It was the 80's.)

They seem to be the same as this:

Wish mine had the air pump lumbar.
