I can help with some of them.
5415-------69-72 Chevelle w/auto trans. upper
5630-------70-7? Camaro w/auto trans. upper
5793-------69-72 Nova w/4-speed trans. and SB engine lower
5795-------69-70 Nova w/4-speed trans. and BB engine lower
The Camaro upper auto trans rod probably went well into the 70's with this number, best to do your own research.
Hope this helps, I have no idea on the other 2 rods.
