There was question as to wether I had a '28-early 29 shell, with the difference being the wiring hole size for the conduit to go through. It is the correct shell for the twolite-three wire harness according to the Standards (pictured crank hole relief). Also pictured is the bakelite plug that would not fit through the hole. If you pull the wire up a little, the wire slips out a hole in the terminal and the plug can be reomoved. The plug is marked "Y", "R", "G" for the correct routing of the wires. Don't know if this is origional or a J.C. Whitney special. I suspect the latter. Thanks for all the constructive advice in this matter. I knew it had to be something easy.
