power column with manual box??? can it be done?

Have done a couple on b-bodies, and found when I just pulled out shaft from p/s column, I definitely had some slop in between shafts afterward. Could feel it at certain times, but I was running solid motor mounts, manual trans, and frame tied. 2nd time I disassembled column, cut shaft, added an extension, and had professional welding shop down the street tig it after I tacked it up. You know, if you are not changing shifter location, the adapter that another member mentioned will take care of both length and coupler compatibility problems. I had to modify my column due to auto to manual conversion in addition to p/s to manual. Steer & gear used to sell adapter.
