thank you sir 
Ok so heres where im at now. The fuel tanks are vitamin water bottles wrapped in .020 styrene. they are technically less than 1/8th of an inch too big, but its negligible i think. (i also have this plastic thats very similar but transluscent that i used on the center area, and the right side fuel tank).
I made one top cap with the styrene, using the upscaled WOF templates. Its going to need to be fixed up a little bit. But thats fine as i'll be making a mold of it anyways as i'd like it to be a separate piece anyways.
Previously the center raised are was extended about and inch so it ends closer to the bottom. I had forgot to mention that. Ive also been using Rafal's measurements he had posted a while back. So far im pretty on point sizer wise. The pack is just about 16.5" wide.
I also added the correct inset on the back for the greeblies if i choose to add them
Im using lightweight spakle to fill the seams and also to coat where the couple of pieces of crap foamboard i had decided to wrinkle and shed its paper coating lol. This stuff is MUCH easier to sand than bondo
So far im pretty happy with this. Much happier than attempt #1 lol.
