I went to Tompkins Industries, a hydraulic hose supplier today, and showed them a sample 1962 GMC K1000 front brake hose fitting and they said they had 729 of them at their Olathe store. I drove across Kansas City to get them and thought I was in luck, but the male part of the fitting was 1/8" NPT pipe thread instead of straight 3/8"-24. The counter guy looked through all types of catalogs to find one, and was looking at ways to use two fittings to adapt it. I didn't want two fittings.

I bought two of the fittings with the male 1/8" NPT and was thinking I'd drill and tap the male end and thread in a section of a 3/8"-24 bolt and silver solder it in. Then I figured out if I removed the threads on the fitting, it would still be thicker than the major diameter of 3/8"-24 threads: .3667. So I will file off the threads on the male portion while spinning in a drill press, and try to run a die down it. I don't have a lathe.

The fitting part number is 6404-04-02. It has correct 7/16"-20 threads on the female end.
