I have an extra sheet of 6061 T6 alluminum I was going to use for my adapter plate, but I got one that was semi finished, so I am going to use that one. These plates are hard to come by, so I would be willing to sell it for 80+shipping (which was what I paid), or if there is interest, I would be willing to make another TII adapter plate using my existing one as a template for $250+shipping.

 

Bump, buyer backed out so it's back up for grabs!
