These parts are not specific the X23B. They are used on many different trailers that all manufacturers build.
Chances are that awing is made by Carefree of Colorado. That's who Jayco was using for awnings on the hybrids in the mid-2000s. There should be a model # sticker on one of the awning arms. Or it might be with the paperwork that came with the trailer if you have it. Then contact Carefree of Colorado, or whomever the manufacturer is.
The AC is probably a Coleman MACK. Take the entire vent cover off there should be a sticker with the model and S/N on the bottom of the unit.
