Carefree awning replacemenr end caps?

[KittyTexas]

One of the plastic end caps broke on our awning. This is a curved arm awning (appears original) on a 1973 24' Safari International. Any suggestions on where to locate one or more replacements (I'm sure the other will break eventually) or should we just replace the whole thing? I really would like to keep the curved arms.

I had a Carefree. When I checked new parts for old Carefree awnings were non existent and used parts hard to come by. I got a ZipDee. They look vintage, parts are available, the manufacturer is user friendly, the canopy is fabric not vinyl and the canopy rolls up into an aluminum housing.
