Need help finding correct size bulkheads

Need help finding bulkheads for my tank.
The return hole in my tank is 1.5" and the pipe for the return is 1". The hole for the overflow is 2" and the pipe i that I have for the overflow is 1 1/4". What size bulkheads do I need?

Sounds like you have holes for a 3/4" return line and 1 1/4" drain.
