Looking for -6AN adapter for PS pump

[ltdmstr]

So I'm doing a bunch of work on my '68 C10 and one is adding power steering in place of the stock manual setup. It's a 250 straight 6 and I have the pump and mounts that I purchase from the classifieds. I'm also adding disc/drum power brakes with a hydroboost assembly in place of the manual drum/drum setup. With this setup, the power steering lines run from the pump to the hydroboost then to the steering box then back to the pump. I figured I'd make my own lines using Earl's power steering hose and connectors which are very nice. The problem I've run into is, the stock power steering pump is 5/8-18 male flare fitting, and all the Earl's stuff is -6 AN. I've spent hours searching for an adapter to go from 5/8-18 male to -6 AN female, but have yet to find anything. I've also spent an hour on the phone with techs at Summit, and they couldn't come up with anything either. I tried calling Earl's several times and despite long waits (45+ minutes), nobody ever answers the phone there. I even tried calling the corporate number multiple times, and no luck. So I'm just wondering if maybe someone has a suggestion on how to solve this.
