You would have to match up the type of awning you have. Should be a model number on the roller. Should be a sticker. I'd look into all the parts you may need and if you can get your arms straightened out before ordering too much. You may find out it's more economical to buy the whole thing instead of piecing together. I had to do that with my old camper by the time I got new arms, roller and fabric I was better off ordering a whole new unit.
May be something to consider.
