My experience from 3 years in a RV dealer parts department showed me that very little on any camper is actually made by the builder, like Jayco. Most awnings are made by an awning maker like A&E or Carefree of Colorado. If you look at the tag on the awning, you should be able to find a maker name and model number. Once you have that, you can go to about any rv dealer, on-line RV parts website or with a little bit of internet detective work, find an actual part number for your needed part, and get it from about anywhere on line.
