Heres the page 1 of that 4/29/68 price change notice
It was not uncommon to include some items previously changed
in with new ones.
look at some of the other dates on price changes.
I like the fact that they left the RA1 price in there and its struck thru.
Today I showed this to a friend of mine who was in GM engineering around that era
and he was surprised to see the reference to Ram Air 2 even in there.
