what do you call these parts

I do not know the proper name for these parts. I bought them when I built my Duster and I forgot what they are called. I am sorry, I have slept since then and my memory is erased. that is what happens when you get old. so don't do it. This is the steering column on a 73 Dart Sport. I need the sleeve that goes up in the column with the little ring on it to the left in the picture. I also need the piece on the right side. has the rubber plate with the cover on it that is crimped. inside it has 2 "H" kinda pieces that is on a pin. Damn I cannot remember what they are called. please let me know what these pieces are called and where to get them. Bill
