Bulkhead question

[billgillette]

So I have a 180g aqueon with overflow. It has 4 predrilled holes which are 1 3/4in how do I figure out what size and what kind of bulk head I need?

Thanks. Does that work for all the holes, intake and return?

If you look at the list, to the right of each bulkhead it gives a hole size.
