The size of each part? Why would you want to know that if you aren't even getting the figure? However, if you actually got your hands on one you could measure it yourself anyway and then make a memo to buy a sticker that size or just buy (spray) paint; it's useless if you want to know the size of each joint so you can buy a sticker that size since you don't have the action figure.
Whats crotch block? *Checks dictionary* Oh you mean the groin block, well I don't know why its not there, I think the main reason is that the mockup company found it hard to make that and couldn't include a groin between the abs and the glutes... of course it COULD NOT BE WORKED ON FURTHER BECAUSE THEN EVERYTHING WILL HAVE TO START OVER BECAUSE THE SHAPE IS DIFFERENT, AND WOULD TAKE LONG ANYWAY... And I know what you will be thinking of when a groin is removed from the original Toribash model...
