Having an issue finding a power steering pressure hose. Everywhere I look it says it's supposed to be a M16x1.5 0-ring fitting. I bought the proper adapter to -6an and the high pressure hose ends/line. However, my pump pressure side only has an o-ring sealing surface and no internal threads. Just a bolt hole next to it like it's meant to be a bolt-on fitting? I'm at a loss here. Engine is a 2010 5.7 from a manual trans Challenger. Any help would be greatly appreciated.
