I may be overlooking the obvious on this here but am back to troubleshooting my issue. I confirmed I do have the shifter box together properly after disassembling again. I am wondering now if I have the shifter handle/shaft mount messed up. The upper mount to the column is threaded to the yolk that moves back and forth when you pull the shifter handle back. That cant be right because its trying to pull the mount off of the column. Are the threads on the yolk not supposed to be threaded to the column mount? I have a few sets of these too so they may be mixed up. Some have different sized and stepped threaded areas.
