69 gmc drum brake front hose question

[65k10]

Howdy,

Rescued father-in-law's 69 GMC C1500 from the field and installing all new brakes. Master, lines, hoses, wheels cylinders, hardware, shoes, everything. The only issue I'm having is the front hose to wheel cylinder. The hose end at the cylinder is an inverted flare and the wheel cylinder is definitely not a flare fitting, looks like pipe thread but is 7/16-20. Is there a fitting that goes between the two? Been to all the parts stores and they only carry the same parts I have. The inverted flare fitting does thread into cylinder (though it is sloppy and I'm sure it would strip if I put any torque to it. Anyone else run into this?

Factory 2" drum brakes front and rear. No mods. Keeping it all original for now. Here's a picture of the hose end that goes to the cylinder.
