I received this "toolbox" link from SAN. Scroll down on the web page and click on your state's outline to open a compilation of the vehicle registration rules and regulations (the "My State" list to the left simply takes you to an area with current events and links to your legislature). I found this very helpful in understanding how Kansas defines the various "specialty vehicles", and that to run "Antique" tags under the law the vehicle must be all original, or with updates necessary for safety (like juice brakes on a Model A would be OK, as would a modified intake for efficiency/power), but cannot have any updated running gear.
