I think it's more of just being willing to work and able to use a tape measure 72 Charger.
Obviously being able to weld is pretty much a must as well. It's actually looks a lot more intimidating than it really is. I think most guys that carry a bit of fabrication experience, have the ambition, and are apt for willing to learn, can do it. I know one thing that makes me more comfortable when I'm sawing or drilling something out or installing/welding something in, is this site and all the great folks with a wealth of knowledge to help me out if need be.
