VIN tag installation

[terrydmorgan]

The VIN tag was removed from my son's 1969 Camaro during the restoration process, and, of course, we misplaced it. I'd been dreading the registration process, as I figured it would be greatly complicated by the missing VIN tag. Well, good news, I found it this morning. Now, what are the rules regarding re-installing the tag? It's rusty and looks a little dinged up. Can I sand and paint it? Are there special rivets/screws that need to be used? Do I need to get the State involved before I re-install (I'm in Texas)? Any advice you can give me would be greatly appreciated.
