On my 68 I completely installed it on the rods, used numerous clamps on both sides and the front and rear to hold it tightly in place for about a week in my hot garage (front and rear glass were out which made it extremely easy). After about a week virtually all the wrinkles were gone and it was easy to work with. Me and a friend centered it up and pulled it tight and glued it in, put the clamps back on to hold it till the glue cured, went back the next day and trimmed off the excess material. Only tricky spots were the back corners to get it wrinkle free. Didn't need a blow dryer or heat gun. In my opinion if you put it on cold, it will sag in the summer months. I would also highly recommend the front and rear glass be removed since the glass helps hold the headliner in place in the front and rear (at least on my 68 it does), and it makes much easier to install with them out of the way. Also, make sure you know exactly where all your holes are at for your coat hooks, etc., before you glue it in. I'm not an expert at headliners (only did one), but this method worked best for me.
