Lost 69 340/Found 1973

I don't have the Broadcast Sheet or the fender tag for my 69 Dart Swinger 340 Vin #LM23P9B33****.If this helps i bought this car near Hamilton Ontario.
I found a Broadcast Sheet for a 73 Dart/Demon Vin #LL23B3B40****,if anyone missing this one for there car i will give it to the rightfull owner.
Thanks
