Harry:
I found mine for my 83 at CROWN AUTO AND RV SUPPLY in Jamestown CA. (209)984-5281. One thing I did do was to take the one that the backup lite is in and run that behind as a second brake light and mounted a driving light on the bumper so I could see when I back up, the stock backup lights do no good in the woods. The part # for the all red is 11152.
