1973 Duster trunk lid torsion bar install?

There was a recent thread but it concerned the 67-8-9, don't know how similar they are. These are not that hard, I'm an old man with arthritis, and I managed OK. I've seen the nylon sliders advertised.

On mine, I cut a scrap broom handle and propped the trunk as far open as I could get it, then installed these while lying on cardboard inside the trunk.

Try a shop manual: Don't know if it's the same for 73. I guess 71 is the latest you can download with body info
