How to remove parking lens in 76 Dart sport grill

Look on the back of the lens housing behind the grill.
There’s probably 2 screws holding the lens on.

Ya there is two screws there I can see them in the lens also but can’t see where the joint is to separate the two. Have feeling it might be glued have to dig out spare grill and investigate as I have a cracked lens I wish to change
