Steering conversion question

I just recently found out about the power steering column, about two weeks ago when in stripped the 73 Duster to be exact. I pulled the roll pin out of the coupler, disconneted everything holding the column in, and pulled. The splines were kind of stuck so I just yanked on the steering wheel. It came out and when I looked thru the hole in the firewall, half of the shaft was staring back at me. It didn't really dawn on me to measure the shaft to see if it would work with a manual box, but I'll throw it on the table tomorrow to take some pics and measurements. I'll try to post them tomorrow night.
