Well so far I have been striking out. Any ideas?

I contacted 3 places for raw 9/16" Amsteel. The first two referred me to the third and no-can-do. It looks like 1/2" is about all I can get - in pre-manufactured winch lines and extensions.

I will have to run some numbers and see what lengths I need, but probably around 150-200' in various lengths (or continuous then cut it up).

 

Have you looked in here for more of the same quality product and just add to the other straps? Garage Sale - AmsteelBlue
