WTB: MC for Baer Track Brakes

[Track Junky]

Just like the title says. I bought a Baer Track Plus brake system from a member here and he sent me a CPP MC and I am assuming it has a 1" bore which I dont like to use. The MC I'm looking for should have a 15/16ths bore. I could use a proportioning valve also preferably from Baer.
