S3 Recaros into A6 Avant

[Inskip75]

Anybody know if S3 Recaros from '52 plate will fit straight into '52 plate A6 Avant - if not what alterations will be needed?

I'm assuming that Recaro made the same seats and they were used in S3's and RS4's and RS6's?

any help gratefully received from those in the know
