Awning width on 1966, 28' ambassador

Our original Carefree awning has a width of approx. 4-1/2' when extended. Was this the stock width for this era/vintage ? I don't know if the P.O. cut the width back. Looking at the extension bars, I would think that another 18" to 2' could be added ? We are currently looking into replacing the vinyl as it is shot ! Mechanics work fine on the unit but we sure could use a little more width.



Thanks,

Danny
