One More Delima!

Ok, I Have Seats (bucket) Out Of A 72 Duster. I Talked To Legendary Interiors And They Said No One Makes The Foam For These Seats The Springs Are Moulded Into The Foam. In Short I Am Screwed I Have To Build And Carve My Own Foam. Has Anyone Done This Or Refinished 72 Seats. All Suggestion And Experiance Is Appreciated.

Thanks
