Carefree Travler Awning

I need some help, I have a travler awning and am looking to find the rollers at the bottom of the fascia arm. These are the rollers that guide the arm up and down in the track attached to the trailer. I just got my trailer back(in laws had no where to stay for a few months), want to get away next week and just found this last night. I don't know why there are not there but there is also a slight bend in the track. I will find out how they went missing but in the mean time need to find new rollers.
Any guidance as to a supplier would be great. Carefree only shows a replacement arm not the rollers.
Thanks in advance
