My recollection is that the 67 Shop manual has all the basic info for body line and maybe engine in the first pages.
Option codes often match with the sales code info, generously collected and posted in the Hamtramck Historical digital Library.

Body info is in the shop manual. Off the top of my head L = Dart, P is cost level, 23 = hard top
Drill through the 1967 Dealer Data Books, and Paint and Trim Option books to get most of the rest.,
Radio code '1' is 421 Transaudio AM (same as my '67)
