50 years ago the junk yards around here had plenty of old cars. Today high rise apartments occupy that land, but that is another discussion. I deconstructed a glove box I may have paid a couple of dollars for. Please tell me if you have questions. I may (emphasize the word may) still have that old glove box in the attic. At any rate, here is a look at the dimensions of the known good box (I'd be still using it if not for the A/C unit because it is still okay). Depth of the box from front to back = 9 inches Top part is where the split of the box is and the top part is made up of two trapezium shapes. The left hand part is 6 3/4" x 9" x 6" and the right hand part is 6 3/4 x 9" x 6 1/8" and the right hand part overlaps the left hand part and is stapled & glued. At the left edge of the left top part there are two 9/16" cuts made to allow the box to bend into more/less a curve and then there is a trapezoid shaped piece formed on the left vertical edge. That piece is 4" x 2.5" and also 9" deep. It has a cutout for the hinge screws which is 2 1/4" by 1/2". At the bottom of that trapezoid are two more 9/16" cuts to allow a curve to be formed and that leads to the bottom piece which is 12 3/8" x 8 3/8" x 9 inches deep...another trapezium shape. At the edge of the bottom another trapezium is formed by cuts in the cowlboard and it is 3/4" x 4 1/2" by 9 inches deep. That takes us to the other vertical side which as you might expect is yet another trapezium formed by cuts in the cowlboard. This one is 3 1/2" x 7/8" and 9 inches deep. On the side of that are the same 2 9/16" cuts to allow a curve to be formed and those of course are connected to the right hand side of the top piece. Some images are shown below. The back side was made by tracing the shape onto the cowl board from the outside and making slits to allow the cowlboard over by about 5/8". There is also on the left hand side a cutout for the hinge screws and at the top there is a cutout for the latching mechanism.
If you or anyone else wants to use this to make an AD glove box, I would suggest saving cereal boxes for the cardboard or just using cardstock or other heavy paper. Cut each piece as I've indicated and use masking tape to hold them together. When all together, this will make a piece that looks sort of like a smile. When you cut out your piece from the cowlboard or whatever material you're using, then use a good ruler and razor blade to cut shallow lines to allow the bends. Hope it helps somebody.
