While I was pulling out my 65 interior for refurbishment I found a partially complete broadcast sheet for my car. I'm having a hard time decoding even the simple codes. It's way too faded for a photo to show up, I already tried. But on the third row from the top of the sheet it says BUILD CODES then it says ENGINE and PINION. Under engine it's missing the first letter but the last two are 12. Under pinion the numbers are 56. What do those mean? On that same line it says under #63 which is shocks it says A. What does that mean? Is there a website to figure out how to decode all this?
