Where to buy internal overflow box?

[eng55]

Picked up a 125 today and it is drilled on the end of the tank at the bottom. I want to buy some type of overflow box that I could glue to the end of the tank. Then put a durso stand pipe on this hole. Anyone got any ideas where I could buy an internal overflow box, not a corner one but the other kind. I've looked online at fosterandsmith and marinedepot but they didnt have anything.
Thanks
