Those hinges are an integral part of the door and I have never seen that listed as a separate part. I would just contact a dealer, doesn't have to be a JAYCO dealer and see what they say. PHILLIPS door and window closed in 2009 and that is who JAYCO used IIRC.
I saw them the other day in the camping section of Ganders in Pensacola. I don’t know if the other Gander locations but they are associated with Camping World, they do accept good sams discounts.
thank you for your help! I did an online search and emailed jayco@parts.com and they sent me a pic to see if it was the correct one and by gosh it was! I will also check at camping world to compare prices.
