Grid of model years and trim levels?

[davepl]

I was wondering if someone could do a list like this:

1969 Chevrolet: Biscayne -> BelAir -> Impala -> Caprice
1969 Pontiac: Strato Chief -> Laurentian -> Parisienne -> 2+2

(Sorry, I only know my old Canadian lines)

But for trucks, GMC and Chevrolet. Some years are Customs, some are Cheyennes, and I know I could piece it together from old threads but there must be someone who can just spit that out from memory...

1972 Chevrolet: Base -> Custom -> Custom Deluxe -> Cheyenne -> Cheyenne Super

That's a guess, but something like that for 67-72 would be great. I can make a graphic out of the info if it's useful to others.
