What toilet flange

[Alcoa Roller]

Well folks I am re moding the bathroom and finally getting to the toilet. I removed the old flange today and below is what I am left with. What is in the tank is rusted and i see no threads. You will also notice that the metal piece in the tank sort has a bowl shape. I will be putting 1/2 ply on top of the fiberglass surface that the toilet used to rest on. It will now rest on the plywood. I noticed some flanges at Vintage trailer but they all seem to want to thread to something. BTW my rig is a 63 Overlander. Please help. If the crapper is down the brain soon follows.

I don't know what the black tank design looks like. Being a 63 trailer it is not likely polyethylene.

Here is what I used. I purchased this flange from Inca Plastics in California. They make just a lot of tanks for the RV industry. This flange fits in a rubber grommet that is a press fit around the hole in the tank.

As I recall I used about a 3 1/2 inch hole saw to cut the hole in the tank using my flange hole in the bath as the drill guide. The tank has about 3/16 thick walls. The grommet is pressed into the tank, the tank mounted to the trailer, and the flange lubricated and pressed into the grommet. I had two 5/8" layers of plywood between the tank and the floor covering. It would be difficult to develop a fange to tank interface leak.

I liked Inca Plastic's design with the flange and grommet.

Thanks DB, Ill check them out. My tank is fiberglass. Its original. Problem is I have the iron insert already in the hole that I am having to deal with. The hole in the metal piece is slightly less than 3" i think I need something that will be like a funnel that leads from the flange on the surface down into that hole. I have had some leaks and now know why.
