Vintage Big Rig Fever............

My uncle took me on a ride along 30 years ago and I've loved Big Rigs ever since. Never drove one but I have around 75 model kits, most still needing to be built. I should get working on those come winter time. I know where an on Dodge is sitting in a guys yard that I'd love to get and restore. He thinks it is worth a lot because it has a hemi.
