Not sure what brand yours is. I was informed that parts for my old Carefree were no longer available last year, so I rebulit it using new A&E torsion spring assemblies. It wasn't difficult, and only took about one hour to modify the new components to fit. The new torsion springs rachet, and lock open, or closed which I like.
You may be able to modify yours too if your inclined. I have some notes and photos around here somewhere.
