brake fitting from ebcm

[demonpixel]

I removed my EBCM, and will replace it with an aftermarket adjustable proportioning valve. I noticed that the two lines that go from the master cylinder have 3/8"-24 fittings for standard 3/16" brake tubing, and removed them with a 12mm box wrench.

The other fitting, though, the one for the rear, is bigger. I had to use a 14mm box wrench for that one (highlighted purple in the pic below).

Would anyone happen to know what size that fitting is? I think I'll need an adapter since all of the fittings coming out of the prop. valve I'm using is 3/8"-24.

Thanks for any help/advice; here's the pic:

Turns out i am completely wrong

I thought they were Standard SAE fittings. APPARENTLY THEY ARE METRIC.

What's labeled as the 3/8"-24 fittings in the pic above are actually M10x1 fittings.

And the fitting in purple is M12x1.5, according to this information:



This is for a 95 Fbody. Mine is a 93 but I'm sure they're the same. If anyone could confirm this information that would be great.
