Black tank box dimensions

In order to get our new 66 trip worthy, today we started ripping apart the bathroom area to replace some rotten flooring/leaking fixtures and a whole host of other issues. In dropping the black tank (that was currently being held only by the foam and the toilet flashing) we noticed that the box that holds the foam and black tank to the trailer was severely rusted and missing the bottom.

We need to get this piece fabricated again, but we can’t seem to find any information on the dimensions of this piece. Specifically how deep it needs to be as we have no section that doesn’t have large sections rusted out of it. Any information on how deep we should make this pan would be very helpful.

Also as a side question, the sluice valve and the vent gas tube (Attached to the black tank on the upper left hand side) were attached with what seemed to be some type of epoxy or putty. Does anyone have any idea what product they used? I can attest that it was very tough stuff.
Thanks all,

The depth on the inside is 6 1/2 inches. I removed my tank on 66. As for glue I would recommend 3M's 5200, here's a link

If your tank is plastic and you need to attach a fitting I would recommend the G-Flex epoxy from West System (any good marine dealer has it). Hopefully the area around the flange is good in your case and you won't have to fix it. G-flex is designed for repairs on ABS kayaks and such and is different from regular epoxies. If you are replacing the floor under the toilet, a tip on locating the whole for the flange. Set your toilet in the bathroom and get it in the exact location as before. Step on the flush valve and then with a long pencil reach thru the toilet and mark the exact center of the hole on the new floor. By doing it this way, you will be able to get the toilet back in exactly the same place. Then remove the toilet and cut the hole for the toilet flange.
