Can you make a Shelby Cobra with the ragdoll I uploaded as the driver? If you need to prevent him from falling apart, just adjust the impulse limit to "+inf". Feel free to make him smaller as well so that he is scaled properly.
@dare: lay off of him, just because you are a phunbox wiz doesn't mean he is. EVERYONE has some trouble at first. And sometimes that difficulty isn't willing to go away w/o a fight.
