Thanks guys, it took a lot of gluing & breaking apart again to get this part square
Heres the modified top jaw faced with the un-modded lower jaw


The pieces just set in....I re-removed the mandibles (I did this mod a few years ago, but could only toe-in the mandibles slightly due to the Jawbox size) and I like the angle they can achieve now

Tis one shows the how the jaw effects how much you can pull in the mandibles

My other baby crying out for attention
