Eddie, I'd say what you have down there is the long nosed gar. They rarely get much over 5' long. The spotted gar is a lot smaller. The gar in that picture is a true alligator gar, and an extremely old one at that!
The biggest long nose I've killed is 50". I shot a 49"er the same day and I bet the 50"er was half again as heavy. One you start getting over 4' they start gaining girth instead of length.
I'm not positive, but I think about the only place you can find gator gar anymore is in Texas.
