Need help with lower horn contact
I'm trying to get my '75's horn fixed and was checking the lower horn contact on the tilt column. When I pulled the hub with stem assembly out (that the spring is connected to), a metal piece fell out of the stem that is about an inch long, is notched and has one rounded corner. Can anyone tell me how this is supposed to go back in? Also, does the rod that is in the stem need to go in a certain way? Help! Thanks!

The is a 1977-82 T&T steering wheel and horn parts. The parts look exactly the same as your 75.
The plastic horn tower that is part of the lower horn contact holds #2 spring, #3 eyelet (looks like a small nail), and #4 insulator. I am not sure about the metal piece that you describe that fell out of the tower. The parts go back into the tower as follows.
The #2 spring, then the #3 eyelet with the upset end first, then the #4 insulator that holds everything together. The spring makes electrical contact with a metal piece on the underside of the lower horn contact. The large spring also must be connected to the lower contact and it also must make electrical contact with the metal piece that is in contact with the spring #2.
So when you are all done with this subassembly. You should have electrical continuity from the big spring up to the end of the spring loaded eyelet that is sticking out of the horn tower.

Thanks Jim. The problem I am having is the stem that the retainer clip in the diagram (very bottom) clips to. That stem has a metal piece that keeps the stem (steering) set and I'm not sure how to reinstall it. Maybe I took too much off the steering column when checking the contacts.

I am still confused as to your problem. The retainer clip in the above picture installs on the very end of the upper steering shaft. It is a safety clip that prevents the nut that loads the steering wheel hub from backing off (if it was not tightened correctly.) This safety clip was introduced around 1975 and was just a "belt and suspenders" additional safety feature to help prevent the steering wheel and hub from ever coming off the steering column shaft even nobody ever tightened the steering wheel nut.
Here is another picture of some of the upper steering shaft, c-clip, and other parts (note, this c-clip is not the same as the retainer clip I just described).
Here is another picture of the steering column with the locking plate in place, the c-clip installed, and a plastic retainer (and insulator) in place.

I think that one of your problems is the order in which the parts go togehter as shown on the Chevrolet drawing in the AIM. The 419454 retainer in the blowup picture really installs above the steering wheel and hub nut. That nut shows up in the picture just above the steering wheel with a line coming from it with the words STRG. COL. and a half black box with a diagonal line through it. I will change the drawing to call out the steering wheel nut.
BTW, the correct location for the steering wheel and hub nut would be just above the Hub Asm 3949110 and then the Retainer 419454. I don't know if I have the ambition to cut and paste the drawing to actually place the nut and retainer in the correct drawing location.
Here is the updated blowup.
