Brake Bleeding HELP!!

[Born Lucky]

O.K. so I have a 1964 C20 with a Eaton H052 rear end.
Here is my problem! I can not seem to bleed my brakes. I changed all my brake lines all new wheel cylinders all around, new brake hareware, new master cylinder. The entire system is NEW.
I starting bleeding the system but for the life of me could not get all the air out. The master cylinder was bench bleed until all air was out.
So, I decide to purchase the Phoenix Bleeding System. Upon using the system I can not force the fluid in, it would blow the fitting off the bleed screw( these was happening in both the rear wheels) so I was troubled. I removed the bleed screw to discover that there was almost no hole at all in both bleed screws. Manufacturing defect, I guess that is why I could not get the air out.
Now I install New bleed screws and I can not get the fluid to exit the master cylinder. If I remove the line from the master cylinder I can get a good flow.
I remove the master cylinder again and bench bleed for a second time, still I can not get the fluid to exit the master cylinder.
I read the manual and it states that the 1964 master cylinder is different that you need a special tool to pressure bleed. Could this system not be bleed with a Phoenix System?
Do I neeed to do something different? Man I am at witts end I want to finish this brake job so I can get plates and drive this thing.
Any help would be great.
