You'll never know unless you try. As with most airlines, it's not all about hours. You have greater than the minimum number required so you get a tick in the box. You don't have to be type rated but, for obvious reasons, they're going to like it when someone has flown the 767 before.
At the moment there's a lot of applicants from the USA but, from the horses mouth, they don't necessarily want people from just one country/background. Likewise, I would suggest that applying whilst still employed conveys the better impression of someone who wants to fly for AJV/AJX, rather than someone who has to because he's got no choice as his airline's gone tits up.
At the end of the day you can't do any harm by trying. A great deal of emphasis is placed on the simulator check, so if you can ace this over someone who's got loads of Boeing time then you're in with a better chance than him. Of course, if you start spitting and swearing in the interview then you're not likely to impress but even the poms that I know can behave themselves for that long
