Help with brake line fitting thread size

Can anyone please help me with the thread size of the port with the green plug in the photo below? This is the rear ABS modulator valve / hydraulic unit / whatever you want to call it... on a 1995 F150. I need to replace the line that goes from this unit to a union about midway toward back axle and it's smaller than the normal 3/8"-24 thread but I don't want to take it off until I'm ready to go buy the replacement if someone here can tell me with the thread size.

Thanks for your help.

I've personally never seen or heard of a smaller thread size than the 3/8-24 for the brake system in my 20yrs of being a mechanic.

I wish i could help

Just measured fittings, smaller one is in fact 3/8-24 and the larger one is 1/2-20. I hunted NAPA's fitting bins and couldn't find fittings, wound up at pullapart and got line off a truck there and salvaged fittings and replaced line.
