Phase 3 seat system

I own an older Pamlico 145T from Wilderness Systems. This kayak has Phase 3 System seats. The covers are torn and sun damaged. Where could I find replacement covers for these seats?

Everywhere I have looked does not carry Phase 3 seats. I have read that Wilderness will not sell the seat systems separate from the kayak? Are there other manufacturers for seats that will fit?

Thank you for your help.

Phase 3 seats
Wilderness Systems will not sell the entire Phase 3 seat system separate. They will sell replacement covers for the backs and bottoms. Most shops that carry Wilderness Systems should have these parts but may not have them on their websites. Get:Outdoors in Greensboro NC usually has these in stock. 336-294-3918

any good dealer can get you the replacement parts.
