Alligator Lizard Sexing! Need help!

[Steve C]

Hey! I need some help sexing some Alligator Lizards... Here's a post about the info....
If you can tell me the sex of them that would just be great... And if they were opposite sex can I leave them in the tank together or should I put them in, see if they mate, and if they do then separate them?
Thanks!

Not that i can sex them but you might want to post the pictures here also. The link takes you to a site that will only allow you to view the pics if you are registered.

Here are the pictures

Also the one with the black backround is 4/5 the girth and is about one inch shorter than the other one, so would I be able to keep them together?
