Rich Marron sent me some pictures that was very helpful gave me something to go on. I sat an looked at this transom for 2 days chicken to drill a hole but now i have one tab installed and one marked to be put on. So i am making a little progress now ran into a snag the nipples that came with the tabs were 2 inches too short to make it into the storage compartment. But now i have that handled all i need is free time to work. Thanks alot everyone.
