Rivage 'Recaro's' front seats

I know we  have a few Rivage experts among the members, so this is a slightly technical question.

The Rivage leather seats are sometimes described as 'Recaro', and to me the bolsters look slimmer than the cloth version seats.

My question is what other VW seats of the time (around '91) are identical in shape eg Scirocco 'sport' seats etc?

(I am looking for a pair of front seat frames (they can be bare frames or with covers) that are the same as the Rivage leather 'Recaros'.)
