Sweet thanks for the help!
I broke the plastic hinge for the rear suspension on one side so I guess I will replace the whole piece. I found a diagram that shows all the pieces on the car here.

I think I need to get part GX53: the rear transmisson housing. It looks to have the hinges on it, so I will have to get that whole piece. Does that look right to you?
Also could you point me to some good cheap wheels that would work for my car that are the same size. I can take the tires off of the wheels I have and put them on the new ones only. I only really need 1 wheel but it looks like most come in pairs. Thanks again!
