Hi Geof thanks for chiming in I now know that my truncklid has come from 65 & has been changed/adapted to work as a 66 lid.The hole has been put in it for the single support rod and the double support rod mounting brackets have been removed the only way the lid has the holes for 4 push buttons is if it was a 64-65 lid so the next question is will you sell the cover and how much? Of course it would also have to be put inside a pvc pipe to protect it what with the age of it thanks for the info Jack
