Interesting. What are the odds of this?

Vintage Mopar has the best odds of any of the big 3/4.

I used to know what it was but I want to say something like 1 in 384.

It's really how many pin heights times how many pin positions squared (or whatever the math term is for the operation below).
IE- 4x4x4x4x4 if there are 4 heights and 5 positions.

My 1986 turbo Daytona was the same cut as my friends 1973 340 Challenger.
