wanting ideas on building a body cart for 70-74 a bodies

thanks for the ideas, guys! I'm still trying to work through this, as I am now thinking it would be nice to make this cart somewhat universal so I could use it on a 67 camaro i will be doing, also. With that said, I am thinking I would like casters that will roll around on my concrete floor while also being able to hook a chain on it, and drag it around the back of my building in the dirt and gravel so I can put it in my paint booth (since it is not accessible from my main shop to move a car in). maybe I need to be looking mmore at the rubber wheeled casters. We have a local place here who sells them, I guess I need to stop by there, and check some casters out, too.
