I just did this on our 2007 19H. After much research, I decided I wanted factory direct replacements. I also had the same problem... no one knew how to help me! I worked with Sherry at RV Workshop (
https://www.rvworkshop.com/contact) and she placed the order with Jayco for me. She will need your VIN number to quote it. I did both for $920 shipped. They are beautiful and were made to order. She was awesome to work with... my canvases were mid-production when COVID closed the factory. I got them the week before my first trip.
