Does anybody have an old slingshot bar/lines lying in a shed. I am after the part that the bottom cleat screws to. Nobody has a spare, Slingshot thinks they may get some in mid December. It is actually called a C loop cleat holder and I broke mine trying to get a broken stainless screw out of it. I have attached a photo ( not very clear)

showing the holder on the left and the cleat which I have.
Thanking you in advance.
