TJR1,
Yea, that's kind of what I was doing, trying too see who has what. Couldn't really come up with a good conclusion. About heating, most everything (but not all) I have read says to bend it cold and don't heat it. It would mess up the temper of the steel, so I am going to give that a try.

Knight,
Not quite sure what you mean by "one coil with 4 loops". The struts are going on a 60 size Top Flight Sea Fury.
On Robarts web site, it only has one loop around, but it is a drawing, not a picture of the product. I see in some pictures of some planes that have Robarts, they are only one loop. I guess I will try that and see how it turns out.
Thanks
