Searching for Reference!

Hey guys, I've been working for some time on doing extra-detailed 1/72 scale versions of my rockets. I'm starting on the Atlases, and I'm running into some dead ends on reference. I'm doing all the stages, including the half-stage section of the atlas. I have great reference of the sustainer section, but not of the inside of the booster section that drops off. Anybody have any pictures of the inside they could loan me or know of any locations on the web? Would appreciate it!
