MASTER CYLINDER

Hate to hijack this thread, but. Master cylinders Nader has a 1" bore. 66 Dart, wilwood a in the front, new master cylinder, best brake 10-1628 off a 78 Aspen. Wilwood prop valve. Can't get anymore than 1/2" of pedal? Bench bled the MC. Now because the way the prop valve sits on the MC studs, I'm assuming I have it plumbed wrong? Firewall side (large reservoir) for the front?? If that's the case, I'm backwards. Will keep me from getting pedal? Obviously I'll change it, but I'm wondering if there are other issues?
Thanks
