Slip and slide transmission

Finally got some time to tinker with it. Turns out the gap in the kick down linkage was only there because the arm on the trans wasn't all the way forward. Used a bungee cord to pull the arm all the way forward and it took all slack out of the cable. I started to try and adjust the front band, but it is not easy in the car. Here are pictures of the linkage (no bungee cord) and pictures of the ID number on the pan rail. Can anyone confirm the year of the trans? IMG_2012.jpg IMG_2008.jpg
