MetroiD, there are Tucker replicas available! Robert Ida makes one: http://www.robidaconcepts.com/lower48.html Chick DeLorenzo who owns the last Tucker ever built was selling fibreglas Tucker bodies, but I don't know if he still is or not.
Brickadier General, if you wanted to put together a Tucker Lego kit to sell, you'd probably find the Tucker Club ( http://www.tuckerclub.org/ ) happy to tell its members about it.
