I did this to my old C20.

When you drive the shaft in 2.5 inches. You have to modify a few things.

First measure the column mount bolt centers. This is how much you can easily shorten. If you want custom the welder will be involved.

The amount you shorten you need to move your park neutral safety switch on the front of the column up to match. You will need to cut slots into the outer column, and the inner column to match.

Then get a piece of exhaust pipe to cover the old hole or water can get in. I welded mine on, but you dont really have too.

My column worked fine the way I did it, but my friend had to trim some plastic to work it. Also the PRND21 slider may not work. Mine didnt work before so no change there.

Then reassemble the unit.
