2007dodge ram 1500 2wd- just changed out clutch, now pedal is spongy,

journeyman, there is no bleeder valve on this system. I know it's a closed system, but I'm being directed to replace the slave cyl only. It would seem that w/o valves to bleed, how would I go about getting the air out? Looks to me that my only option is to replac with a pre filled sys.

If there is no bleeder screw on the slave cyl which I find that hard to believe then get someone to pump the clutch pedal and crack the line going to the cyl
