Not funny. Jumped in my turbo the other day and landed on the floor!

The arse fell out my drivers seat! I had a look underneath and theres a big rubber square that holds all the stuff in the seat up and it has snapped down one side! Is there any way of repairing this or do i have to get a new seat? Its 90 spec recaros. By the way i have a clutch box holding it all up just now

and I work in a Ford garage but the part is now discontinued
