Recaro seat foam

[67RSRAG]

Hey guys can anybody suggest a place that I can get foam inserts for recaro seats. I am looking to customize some seats for the rear. They will be cut and modified so I see no purpose in buying a new seat and cutting and throwing most of it away just to end up with a modified foam seat. I am having a hard time finding suitable used seats, and the cost of shipping them is cost prohibitive.
