Here is an updated matrix. For the part numbers in dark green the pattern has been confirmed. In lighter green, it is likely the same, but unconfirmed. I do not have any pictures or examples for '66. Also the Chrysler 300's (C-H, C-P) do not list a trunk mat, but some have described as a black rubber mat with ribs (un-confirmed with pictures)
Dodge seems to be pretty well confirmed.
'65 has a herringbone plaid pattern, '67 & '68 have a small herring bone pattern and '69 has a plaid that incorporates stripes or straight lines.
Please keep the missing info coming.
Green shading means the pattern is confirmed.
