Travel wagon pop top seals?

Has anyone restored a travel wagon pop top? I need a source for some new rubber seals for the camper top. They are pretty unique and Ive had no luck locally finding anything remotely close. I know as a last resort I can pay the big bucks for some one off seals, but I would really rather not if I could help it.

Can't help with the seals, but that van is about the neatest thing I've seen in a while! Really fun ride!

Steele Rubber -get catalogue=free--- I jave 2 vans 61 econo & 67 Chev gen2- both with Travel Equip corp. did these tops & complete conversions. Ill be replacing these seals also tghis year. I am also considering using some old fire hose as inside is rubber- yet havent made up my mind as tops are not off as yet.
