Special effect question

Okay, I really need some help with a prop I will need for my movie. No need to be special effect experts, this actually has more to do with display or clothing.

So what happens in this scene is a man is thrown to the floor and disemboweled. I have the way I wish to do this. First, I get some plasterwall and cut a hole in it, where my mate pops his head and arms through. Attached to his head are one of those clear plastic torsos they use in shop displays and his legs are stuffed. A hole is cut in the clear plastic torso and a hole is cut under that also. Under the plasterwall is a bucket full of blood and guts.

Now, what I need know from the brilliant dopers here is how I could get one of those clear plastic torsos for little or no money. Really, I have no idea. Will I be able to get some from a shop supplier or something? Please help me here.

Thank you.

Whatever you do, don’t buy one from Steve Guttenberg!

Have you checked a large educational supply wholesaler?
