Steering shaft diameter

Dana67Dart have you done the swap yet? Wanted to se if you could measure the p/s shaft. I bought a p/s floor shift column from a member, I rebuilt it and just tried putting it the car (68 barracuda) and it’s 1 to 1 1/2 to short. From what I’m understanding the shaft is probably collapsed a bit. Here’s a pic the coupler pushes in and out about 1 1/4, the column is bolted in.
Thanks
