Those are my seats; I love them. A PO installed them in the 80's along with Simpson seat belts, stahl headers, webers, bigger sway bars, bbs rs wheels, etc... All cool period stuff; I've kept most of it except the seat belts.
David,
Thanks for posting the link to that website. Now that I've already had my Recaro 101 class this morning; I would agree the backs are the LX style but I'm going with the D bases (since my seats have the adjustable thigh support).
