It would be rather helpful if somebody could post the dimensions for each body texture, i am guessing they might all be 128x128, but i am not sure

Yes they are.
For example, Ducky Base is that size, you could have just searched...

They are way over priced... I'm not going to pay $25 for a left shin texture.... That's more expensive than the head! I mean, I'd actually pay real money, maybe $10? For the whole pack (With out the head texture of course).
