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:

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.

Yeah, they are the same.
The EBCM is a computer under the dash. What you removed is the ABS unit (or as the diagram calls it the "brake pressure modulator valve assembly").
