Sorry - I glanced over that bit. Danno, a Performance Catamaran dealer should have the pre-bent rudder arms for about $28 - $32 each. You will have to drill the rivet holes for the castings but I suggest you consider the time you may spend trying to make new (heavier and less corrosion resistant) ones. If you can figure out which one is bent too much, you could possibly just replace one. The rudder arms come with no holes in them so you can place it on the left or the right side.
