yes, and that is already possible with the GM steering column, it has a hole in one side of the D stub that sticks out, so you can insert that one long set screw in that position and tighten it like borgeson requires against the undrilled side. I have used that exact same u joint and collapsible shaft on 6 trucks. I dont think I have gotten it wrong yet but anything is possible I guess.

the reason for it at the top joint is because if a set screw falls out the direction the shaft will fall away is down, away from the column. a through shaft adds a measure of safety, you will hear that long set screw clattering around long before it falls out and the joint falls off.

when I look at your side by side with the old one, it looks like the collapsible shaft is fully collapsed and the right length.
