I've got one. Shoot me an email at EarlyBrds@aol.com and we'll work out the details. I did the same thing on my 67. I had the glove box lid off and it was painted at the same time as the dash was painted so that they would match. Then it somehow came up missing when I went to put all of the parts together. From parting out Firebirds in the past I ended up with several of them.
