P/S box fitting

Before i go and have a custom hose made. I thought i would see if someone has the fitting i need. I'm looking fro the fitting on the top of the P?S box on my Dart, I need one that screws in the top and has a female w/o ring for my P/S hose. The one i have is for a male flair P/S hose. i think the one i need is off a later model like 74 and newer. Thanks
