has anyone ripped off a vinyl top on a 78 regal? I want to convert mine to a hard top, and ive heard all kinds of stories from easy job to difficult. I read a posting on the threads here and it made it sound easy. (theofloorie? converting his 78 vinyl to hard top) Was the 78 finished under the vinyl or is it un welded ? Difficult to remove adhesive ? back window chrome trim still fit ?
