So my girlfriend and I bought a 1973 . This thing is in pretty good shape. Tent has no visible tears in the canvas, but somehow I can't get it to connect or stay connected if I'm connecting it right.
Hope you are having good luck setting up your pop up as these can be very nice to use.
I did find a video but some of these do not always answer specific problems but sometimes you can gleam something from them.

I also found a link that you might find interesting - just in case you want to know if you got a good deal:
