It was super easy on first one as foam came out perfectly without damage. Then using headliner glue from oreillys. Glued and cut extra all around so could be folded under. Popped headliner with original foam in place. No glue on foam. Fit tight and snug. Will try a couple more today
Just popped two Headlines out today....got it started on rear edge and then slipped hand under hard foam lightly pushing further under Headliner foam. Gradually the foam headliner popped from the edges without any failures. The old Headliner with foam came out perfectly (one was originally not glued). Now simple to install new Headliner on original rigid foam and pop Original Foam with New Headliner back in place tucking New Headliner in under Original Foam as I pop foam in place.
Maybe Too Many Foams and Too Many Pops but you get the idea
