I've started replacing the headliner in my 63. Tore the old one out today along with all the mouse droppings etc. ( Dirty Job) My plan is to start at the rear when installing the new one and work forward. I've had it laying out over the roof of the car for about 2 weeks to try and get the wrinkles to relax as much as possible. Then will use a heat gun on the low setting to get out any remaining ones when installed. I numbered the bows as I removed them. Any other hints before I get started from those who have done it before?Paul L.
