I have a spare, BUT it matches my sq. tubular alum. rudder casting - I'll have to check this against Mike's or John's newer cast-alum. casting, to see if it matches... unless your casting itself is made of the same square alum. tubing as the rudder arm, in which case I know it fits, and you're welcome to my spare. I'm sure we can figure something out, though.
Let me know which it is.
See you guys this weekend
