Converting rear to disc brakes, need help on fittings at the stock prop valve

[UATahoe]

So i am converting over to rear disc brakes and i have purchased a new Wilwood master cylinder and the wilwood prop valve that mounts alongside it. I know i need to ditch the old stock prop valve that is mounted along the front cross frame but i am looking for help on the type of fittings i will need to couple all of the lines together. Since i am ditching that stock prop valve i need to connect all of the hard lines together respective to the incoming line. Anybody know of some union couplers that would work? I am guessing the incoming fitting is different from the outgoing. I suck at explaining things but hopefully some of that makes sense. LOL
