Okay, I bought this adjustable prop valve a while back thinking I would need it for my LS1 rear swap. Well, I didn't, but since I have it here still, I figured I may as well put it to use. Now, I know how to gut the prop valve, but I don't know the sizes for the brake line fittings into the stock valve. I was either going to just get some adapters and plug the current lines into the new adjsutable one and bypass the "rear wheels" front ports on the stock valve, but I'm thinking I'll just gut it and put this inline with it.

The inlets on my adj prop valve are 1/8-27 NPT.
