Great site and like Matt mentioned I doubt the F-15 and F-16 claims. According to my sources only MiG-21s scored during the Bekaa Valley "slaughter, although the Syrians claimed a number of aircraft.
I just went back an looked at some of the pictures of some of the aircraft claimed to be shot down by MiG-23. Something interesting...

Check out this shot of an IDF F-4 with its canopies opened.
That piece of canopy may be the front windshield but I see no frames on it. Any thoughts?
Here's some more F-4 shots
