Any Takers!
I would do it in two pieces.Having one piece bigger than the other so you can fold it down like a tent trailer,one covering the other up.This way the two pieces slide into each other and can be put into the glove box and opened and screwed into place.This is done with counter sunk screws to give a flush finish.I would order a new glove box and get the right dimensions and do some trial fits,and a used dash to try it on.Mrmopartech
