Tips to install cardboard headliner?

Al,

We didn't purchase a new headliner. Ours is in pretty good shape so we're just going to just paint it and put it back in.

Jerry,

Thank you for the pics. I agree they probably aren't needed one the trim is in place. But I can see how they would be helpful until then. :-)
I don't have anything like that in the parts that came with the car, but I seem to recall something like that at Ace hardware so I'll check it out.

Thanks,
Ken
