67 barracuda glove box removal

I'd be a lot more worried about preserving the sheet than the box. Cut the back of the box off to get the sheet out intact and then replace the box - if you get one from a later dart (74-6?) they had plastic boxes that folded down and even worked better as a glove box

Thanks STR, The broadcast sheet was attached to the back of the glove box with two pieces of tape. The glue on the tape was dried out so the sheet detached from the box easily. The sheet is very brittle, and so was the one I found under the back seat. I will preserve this one as I did the other.
