80gallon need help for my drains

[luda2001]

Hello all!
So I acquired an 80gallon hand me down. Cousin had for about a year or so, he’s getting out of the hobby for a while. Anyway need help/advise the way he piped the drain he had the drain on one side (bulkhead) and the return on the other bulkhead. So my question is how can I go about fixing this I’ve tried to read the measurements on the bulkheads they tread about 1 1/4 reduced to 3/4i believe. I’ll have to double check in the morning. IVe been trying to look up to see if any overflow boxes would work/fit but unsure. I don’t want to purchase then them be incorrect. Any feed back would be much appreciated thanks for ur time in reading this. Sorry it’s long

It looks like the tank is drilled for a standard overflow box, so you'll have to get the measurements on the tank and find a box that fits, or get a blank box and drill it yourself. If you can get the measurements, we can help locate the right solution.
