1966 jeep cj5 rolling chassis with no title

does any body know what part of the jeep the title goes with

Sean,
For all practical purposes, the title should stay with the chassis. A CJ5 should be stamped on the frame with the serial number that matches the title. he body tag is screwed on, so often times it is lost or goes on to a donor body. I know my wagon has the serial number stamped on the passenger side top frame rail, just before the shock mount.
