Ill try to see if I can find a pic, I have some somewhere from when I installed the extension box that may show it

Thanks Smitty.

I cant seem to find a pic of the bilge with the mounts BUT if you look at the OPs link in his first post, you will see the mounts (billet with post) and then picture putting 3" x 5" 1/2" thick aluminum L angle about 12" long down one stringer on each side with a similar sandwich plate on other side of the stringer

I was going to make a 1/2" aluminum cap (3 sides) that slides down over my stringer, through bolt it with sleeves epoxyed into the stringer. I wanted the stringer in a metal sandwich LOL. Then use a recessed bolt through the bottom of the plate to hold the mount too. I was thinking of also adding some 5200 to the plate too but I know it might never come off if I ever needed to remove it.
