carefree awning fabric width

[johnhh]

In the interests of cost control, I am installing an old Carefree awning onto my '78 Tradewind. Cathy has the sewing machine and stuff to make the awning. While i refurbish the arms and cut down the tube we would like to get some Sunbrella awning fabric on order.

However, this old Carefree awning did not come with the fabric. Does anyone know or can you measure what the width of awning fabric should be? I can figure the length of the fabric (the centerline of the arms is 15 ft.), it's the width of the fabric, from the top awning rail to the awning roller tube, that I need some help with.

Thanks, John H
