Ah, I see them now, My devilles have dealer emblems on the drivers side, They are metal and look like the Cadillac ones, not just a cheap sticker. I was also expecting a Fleetwood badge on the rear panel of the drivers side, but saw in the pic of your fwd thread that yours has fleetwood in the front on the chrome strip.

The only thing I have used the jumper cables for was too remove a hose clamp on a heater hose when the hose broke. I thought it was pretty genius lol, Just used one end like you would use pliers lol. Never had to jump it.
