Hi,

I am looking for a source of 5/16" aluminum square tubing with 0.010 walls as originally used on the Stinson Reliants, SR-9C.

If that is not available, where can I get 8 foot sheets of T-4, 0.010? (only if I have to make my own square tubing.)

If that is not available, I am open to recommendations on 5/16" square material that I can use, and the supporting FAA basis.

These pieces span from the leading edge to the tailing edge to provide the airfoil shape to be covered by fabric.

Thanks (I also have 3 Reliants to return to service)
