It's a Chevy steering column (mostly) and there are numerous write ups for this problem. Here are a couple, though they may not be exactly the same they are near enough.

I usually put a board up on two saw horses and lay everything out in the order of removal, makes reassembly much easier. If you pile all the pieces in a box it can get complicated quick.
The only major problem I had was getting the connector apart for some extra wire to move the turn signal switch assembly out of the way ( I broke my connector). And some trouble with reassembly, there are some parts that really don't go back together logically and can cause brain lock.
Not correct, but good enough, is to tighten the two bolts you can see for the tilt mechanism and forget about disassembling the tilt mechanism to get at the hidden bolts. Like I said, not the right way to do the job, but it has worked for me twice now and lasted for years.
I've done it now half a dozen times on various Jeeps and Chevys, it gets easier, the trick is to take your time and be careful, the plastic pieces get old and brittle and are easy to break and keep things organized.
