Emblem trouble on my 1981 Cheyenne

[Dasbaby]

I was passed down this 1981 Cheyenne by my grandfather last year and have been working on it for awhile. There was a large crack on the drivers side exterior emblem since I got it, but I hadn't had the time to fix it yet. Today after coming home from work I noticed that the emblem has split into two entirely separate pieces. Unfortunately I can't find this emblem for sale anywhere, so buying a replacement isn't an option. Anybody know a good fix for this?
