I have sent Treadwell a message. Thanks for everyone's input.

I know im getting older but I
remember the Rockers Tabs that we
installed a few years ago were
under the boat and Howard sent a
insert that had to be setin the
mold.
Those in the photos are mounted
like trim tabs on the transom.
Might call Rick Wimp @ Arnison 415-485-0788, He was on this board
but haven't seen any posts in a
long time now.
