Thanks for all the input guys. I had actually saved my old headliner that I took out of the car about 18 years ago and had left the rods in it. Made it very easy to know where to put the rods into the new headliner, just switched them over. I actually have the headliner installed into the car, have all the windlass cut to size. My biggest issue is getting out all the wrinkles. The headliner I am using is from PUI and has been in a box for about 10 years, so there are fold lines in it. The glass is in the car and it's also in the 40's here right now in Michigan. I am thinking I may just do a loose install on it, no cutting or trimming, and just wait until June where the weather will hopefully be better. I like the idea of a steam iron though, but not sure where to pick one of those up. I also thought of maybe putting a small space heater inside the car, close the doors, and just keep an eye on it. Get the interior to about 85 degrees for 15 minutes then jump in and start stretching. I also have a good heat gun too. What do you guys think?
