i have owned both cars since 1979 and i dont think the gray car was ever painted. i know it has the 73-74 stripe on the sides. it was made late june 72 so i dont know. maybe someone ordered it that way. you can never tell, they did alot of one ofs back then. i just know they are mine and will not part with either one. hope one day i can restore the gray one like i want it. it still has 1981 plates on it. i push it out every so often to bathe her then put it under the covers. lol. if i can just get this damn house paid off lol
