1972 chevy k20 front brake hose info?

[low1954]

I'm am looking for answers!!! I am trying to find out
The thread size of the fittings on my front brake hoses. I have
Found out that the side that bolts to the caliper is a 7/20 banjo bolt? Is that correct? However I can't find what type and size of the fitting that is on the frame side. My truck is a 1972 chevy k20. I am wanting to know this info
So I can make my own braided lines. I have the braided line, but need to order
The correct fittings. Any and all help would be awesome. Thanks Jeremy
