bcuda power vs manual steering column tech-pls help!!

hi
from what i can see--1970 barracuda
the manual steering column is 3/4 inch longer with a bigger inside diameter steering coupler.

the power steering column is 3/4 inch shorter and smaller i.d steering coupler.

these are different because the manual gearbox is smaller and the shaft needs to be longer.


also--can a shaft be swapped out?
what do you think moparts??
thanks
