Looking at the gallery images it typically appears that the top edge of the shoulder bells are just slightly higher than the horizontal plane that the top of the chest armor would create. If that makes sense.
I tried the foam, worked great. So far I have one gauntlet painted and the keypad (Does anyone else think its funny that the keypad is just a calculator keypad?)
Took Boba out today. Utter disaster. Forgot the girth belt, ammo belt didn't fit after all the layers were on, braids won't stay on, a shoulder pad fell off, and the tubes stuck out too much.
