I have one 316 SS mast base organizer.
Originally fabricated to fit an Aloha 8.2, it may fit other models.
The flat section used for mounting will accept a mast base with maximum dimension on 4-3/4" x 7-3/4".
Eachi side has seven 1/2" holes for mounting blocks and there are four holes fore and aft.
Asking price is $75 Canadian + buyer pays shipping.
