Hydro Boost Push Rod

[6600DURAMAX]

Installing my hydro boost setup and the rod that goes from the brake pedal to the unit has threads on one end that I can attached to the factory threaded end but the other end is just rounded and goes into the back of teh hydroboost unit a little. It has no way to attach it. Is this normal. I was at first worried it could come out but after careful examination if it is in there tight (like it should be) the brake pedal cannot come back far enough for it ever to fall out so I guess it will be fine like this??

Also is there anything special I need to do to properly bleed this system, everything is new, ps gear box, hydroboost, m/c prop valve, all lines etc..


thanks guys
