Steering Column Help

Just a further update. I haven't found a use for those two bolts. The donor column had them too, but again, they just seem to be attached to nothing.

I've attached a couple of other pictures of the column. Right now the problem is as follows, I can pull the shaft from the top (notice the vicegrips at the bottom of the shaft). I figure if the shaft is locked in place, it will keep the two collars together. Alternatively, if the two collars could be locked in place, they would keep the shaft from being able to be pulled out.

Any ideas?

Thanks as always.
