Re: Front brake hose fitting 74 C20

Is it for a 74?...most likely not metric...maybe...
Are you referring to the line fitting size
I'm guessing the line size will be 3/16...which most probably will have a 3/8-24 thread size fitting on it.. be aware, you can also get different thread size fittings for 3/16

Or are you referring to the od threads?

It’s a 74 C20 cross member, going into my 63.

Just not sure what fitting I need to go to the brake lines.

Hoping someone here can post a couple pics.

Should be 3/8-24 inverted flare brake line fittings
The ends will look like this

From the factory, a stamped nut was used but you can use a 5/8"-18 nut

I think I can just use what’s on the truck when I swap the cross member.

5/8-18 jam nut to hold the hose to the frame and regular 3/16 brake line + fittings for the hard line
