steering column question

[BOHICA-Chevy68]

So I did a search, but this is something that may be hard to search for so I fgured I would give up and ask. I put a Automatic Trans in my 68. It origin had a 3 speed on the tree and the P.O. put in a TH350. Then I put in a 200-4r. However when the P.O. did the swap, he just welded on the orig steering column (and did a horrible job) instead of switching the columns.

So i found a 69-72 colum that is a automatic column, but this style column has the two peice shaft, were as the 67-68 column had a different desing for the "weak" point when involved in a accedent. So my question is; can i remove the two piece internal shaft from the 69 column and replace it with the shaft from the 68 column, instead of buying another intermediate shaft to complete the column?
