Holy crap, I almost lost my cookies navigating through the huge picture in your original post. Great resolution, though,

I think your questions have been answered. I did notice, however, that your left hand IC mount shows a crack. Mine did the same, some previous owner helicoiled it, but still it eventually broke clean off....uh-oh. I drilled it, tapped it, applied JB weld and screwed in place a long enough stud to mount the IC to. Just something to tuck away until the day comes that you end up needing to repair it
