Bendix MC pushing nothing to front

Removed what I assume is the original master cylinder following an attempt to bleed the brakes. Was getting good pressure in the rear brakes and moving fluid through the lines. Fronts were barely dripping and then peddle went to mush and I can’t get anything built up. Pulled master cylinder and found when I plunge the rod, only the rear is pressurized. Nothing coming from the front but a trickle. Pulled the plunger but I don’t know what I am supposed to be looking for on that. Is there a tool to remove the fitting from inside the brake line hook-ups, I think it may be plugged. Any advise, or would it be better to just replace the whole thing? And with that, what’s the best way to remove the rod for reuse with the new MC? Don’t think the new one come with rod attached. Thanks
