What size bulkhead do I need if my tank is drilled with 1 3/4" holes. Also, should it be threaded on the inside or is it better to have the smooth inside for my overflows. Unfortunately the hardware stores around here don't carry them or I would just pickup a few and return what I didn't need. Instead, I have to order them online. Thanks for the help.
Bulk head question.

Bulk head for that hole would be 1". I had nothing but trouble with threaded bulkheads. It's better to have double slip bulkheads that way you know they won't leak if glued on. Here is link to bulkhead: http://www.marinedepot.com/Double_S...kheads-Plumbing_Parts-FT1151-FIFTBHDS-vi.html
