I had a deep tuttle mast and a medium tuttle board...So I built a shim in CAD and my son made it for me on his 3D printer. Fits perfect.
allesad , This is probably the only way to do it , I got ready to cut mine today but found out I had to cut all the way to the brass bushing , following your idea I could shim using marine tex epoxy and sand it downuntil it fits good in the box . Thanks for your tip .
