I am a fan of the new Zica body. I put a Mattel Superman suit on a Zica body and was truly impressed. The Zica body has a great Golden and Silver Age vibe to it I think. However, I felt that the body would be even better (for certain characters) if it had some larger shoulders and arms. So I got out the x-acto (cue mad scientist laugh here)......
As you can see, the Zica body is constructed much like the poor wrestler here. (The wrestler was on sale for 7 bucks at TRU part of the Cyber Sunday line)
Here are three arms I have, the one one the left is a large arm I wanted for Thor, I think it may be too big! The middle one is the new wrestler and the one on the right is the Zica arm. Notice that the smaller wrestler arm has the same size round peg top on the shoulder joint. (the big arm would need to be trimmed to fit)
close up of the Zica chest with the new arms. I used the white spacer in the shoulder joint from the wrestler because I thought it filled the space better than the Zica spacers (The round peg top seams thicker on the wrestlers arms).
Here is a shot showing the chest and waist. It is a bit tricky putting this back together because the chest goes inside the waist a bit.
