New Heater Hose and Bypass Fittings

I ordered and received a set of new 1969-down heater hose/bypass fittings for my Barracuda. One of them is a LONG fitting.. where the heck does that one go? I've looked for a picture as an example and can't find it. I know my waterpump has been replaced on my 1968 318 before so I can't use it as a reference. Anyone seen a long fitting like this used on a pre-69 small block?
