Well, I can't remember how to "downsize" the pictures I took off my phone, so I will try to describe what I'm seeing.
With the coupler just barely engaged on both splines of the steering box and the steering column shoved all the way forward against the dash, the pivots just barely touch the coupler. I'm about 1-1/4" too short to connect the pivots/shaft into the coupler.
I pulled the steering column out of the car and measured it. From the end of the shaft (no coupler) to the edge of the outer tube is 7-7/16". From the end of the shaft to the edge of the tube with the lockout (not the lockout itself, the tube) is 5-15/16".
I think it has been collapsed about 1-1/4" to 1-1/2" for sure. I like the idea of drilling/taping the holes where the shear pins go, screwing in some nylon bolts and then cutting them off flush to make my own replacement shear pins.
Where are those shear pin locations? Will I need to disassemble the column again? Does anyone know how to do this? THANKS FOR ALL THE HELP!

All 68-70 B body steering column shafts are the same length. The 1970 piece needed to be modified the accept the split pin for the "star" lock wheel.
Manual shafts are 44 1/2" end to end, if not collapsed. The part #244515, is labeled on the steering wheel end along with a white paint I/D marker. The length of the gear end is 7 1/4" from "spin-weld" to end. The manual coupler has a 3/4" splined hole.
Power steering shafts are 41 1/2" end to end and have a purple paint marker. The length of the gear end is 4 1/4" from the spin-weld to end. The P/S coupler has a 5/8" splined hole.
After retiring from Chrysler, I started Premium Interior Restoration, and have restored over 175 Mopar columns. I have lost track counting the amount of "modified columns" that I have restored/returned to O/E design intent.
Any one may pm me if you need info related to restoring your steering columns. Mike
THANK YOU MIKE!!! My power steering column center shaft measured 39-1/2" end-to-end......about 2" too short just like it looked like under the hood. I put some vise grips on the inner shaft & drove it out with a hammer until the plastic shear pins lined up (drilled out visible plastic). It's interesting that the ends of the shear pins looked totally OK & I would have NEVER figured out the center shaft was partially collapsed without measuring it. Looking at the surface rust, the donor car was in a front end accident a LOOOONNNNGGGGG time ago. I plan to drill/tap the holes, run some small plastic bolts through the holes & cut off the ends to make my own replacement plastic shear pins like one of the other members suggested. THANKS EVERYONE!
