Still working on my 73 cuda, it came with a vinyl roof at one time, long since gone. Was interesting as I was stripping the room and there stamped in the roof are in 1/4" letters. MAUREEN JOHN HEATHER and some others I can't make out yet. There are lots of grinding marks. Apparently ground to help the glue and tops adhear better. It must have been a slow night on En2 when this was built.
