I know it is a real long shot, but miracles do happen, so worth a try.
I am looking for broadcast sheet for RM21J9A240932.

I swapped my bench seats out for 69 GTX seats in 1971 while living in Jennings, MO. Back then no one thought about such paperwork. I still have this car and am looking for it after all of these years.

Any help is greatly appreciated.
