Found a broadcast sheet in my 69 Dart GTS 383 4-speed car that I have owned for 25 years! I had taken the interior out a couple of times and have never found another broadcast sheet until I had my seats redone, and this sheet was inbetween the buns and the seatcovers - LS23P9B336611. It is an F8 green 340 car. If you own it, PM me and I will send it to you.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
