On my '70 Stage 1, I had 2 different ones. They're both rather obvious. 70 STAGE HEMI KLR I still have the plates but not the car. Now I'm looking for the car to match the plates.
Nice. My father-in-law has "SNKYSNK" on his '08 Viper. There's an old song he likes, called "Sneaky Snake." A little bit of topic, but close enough: I had "Corvettes are for Breakfast" on the rear license plate frame on my '71. It usually worked up the guys in Vettes, especially one guy in a yellow mid-90's LT1 convertible who couldn't catch me to save his life. My '71 Skylark was a yellow convertible too. I'm thinking "Heartbeat Breaker" as a plate frame for my current '72.
My all time favorite was on the back of a car owned by an endocrinologist (that's a gland doctor, also a kidney specialist) that read: 2 P C ME
John, I've had a few people mad at me because I have this plate! Maybe I'll wait until the car market comes back around and auction it off to the highest bidder! LOL (Maybe the whole car, plates and all!!) Steve
There's one of those near me too. If I recall correctly, the Brand name appears directly below the license plate on the bumper, so it reads perfectly.
