hi artb- i was there too. in fact that year was my first tire change when i helped my father change a tire on his 48 plymouth while it was snowing ,just like ralphie in christmas story movie. even cussed when the X wrench spun and hit me in the beak. pop asked where i learned that word, told him from uncle moe. you have no idea what a firestorm that created. art since you were there , bet you cant remember the original prices in 55 for burger, fry and small orange fizz. regards oldduke ps- while you are cogitating over that will give you a hint- big mac was 45 cents.
