Power Steering High Pressure Adaptor

Hi, i recently stripped the adaptor for the high pressure line into the control valve in the power steering gear box.

Its a 66 Fury 383.

Anyone have any ideas where i can get a replacement adaptor from?
i went to a hydraulic place locally but he didnt really give me any help, just confused me with the different type of fittings and asked to see the pressure line, which ill bring into him tomorrow.

But any help on where or any information at all would be helpful.

Ive attached some pictures that hopefully help.

Thanks.

Shaun
