another brake question 70 c-50

[sick_46]

I am trying to get my brakes working on my 70 c/50 without converting to hydroboost. I have the master cylinder on the firewall and the booster under the cab. I replaced the master cylinder and began to bleed the brakes. I got good fluid from the remote master under the cab. then went to the rear. both the rear bled out fine. the fronts however will not bleed. i removed the bleeders completely to make sure they are open and not clogged up. they are clean and I can blow through them. but no fluid comes out. I cracked the line where it splits and goes to the 2 front wheels and I am getting good pressure there. I am thinking its either the rubber hoses going to the front wheel cyliners are collapsed inside or I have a wheel cylinder problem. Has anyone experienced this before?
