Whoever said it "ain't gonna be a BDR" is wrong. Many states have very legal ways to title cars as pre 1973.
The Backdrafts handle great and would make a fine choice for your 1965 titled car. There are plenty for sale on this site and on
http://www.cobracountry.com/home2.html. In fact, there is a new listing for a 1965 one there now. Or call Jay, Bill or Reg at the one of the dealers, they will sell you a new with a warranty.
