Steering Column Removal

Hello all
I have enclosed some pics. In order to remove the steering column do I remove the 2 bolts on the smaller flange, or the three on the larger flange?
Also this car was automatic on the column at one time in its life. Now I will have a real problem removing the steering column as the shift linkage is interfering with the header tube. I dont even think I can get a sawzall in there to cut it off.
Another note I purchased a tool from American Muscle to remove the lower control arm bushing outer diameter shell. This tool worked perfectly, I had the sleeve out in 2 minutes.
Also I installed my upper control arm bushings, with a tool purchased from the same company
thank you for any advise
its cold here in Connecticut today
