69 L78 Tranny question

[JRSully]

Heard a blurb somewhere that if you ordered the L78 with standard tranny and didn't specify which you wanted exactly, the formula the assembly line used was 3:55 or higher rear gear, M-20, lower than 3:55, M-21. In 69 the M-22 was available, had to be specifically ordered obviously, M-22 was not available in the Nova for 70, never heard of a 3pd in a BB Nova. I have no idea if this is fact, just what I heard. SULLY
