[1956cameo]

So I have another technical question that I am hoping someone can help me with. While working underneath my blazer I noticed that one of the previous owners took out the transmission cross member. No problem I thought, I have a parts truck with one in it I will just take it out of there. So I unbolted the transmission cross member from the parts trucks frame. Unfortunately all I am able to do is slide the cross member forward or backwards about 1 foot. I am have no clue how to actually get it out from between the frame rails without cutting something up (which I refuse to do). Does anyone know how to take the cross member out without cutting something up? I see cross members for sale on the forum all of the time so I know it can be done.
