A number of threads, on FCBO and other C-body-focused boards, have wondered over the years about the A07 code on some 1971 Polara's and Monaco's fender tags. While there are plenty of entries for earlier and later model years, either most online decoders (whether automated or lists) are silent about this code for 1971 or they call it the "Turnpike Package". A simple search shows a number of FCBO threads accordingly making a reference to one or the other. I find the online decoders' claims puzzling because (i) some of them "specify" that the Turnpike Package entails a 383-2 engine yet (ii) I am aware of at least two 1971 T-code Monaco coupes whose fender tags both contain the A07 code. I submit that the solution to the riddle is on pp.5-6 of the 1971 Dodge Polara & Monaco Salesman Pocket Guide. I am attaching below an extract of the relevant portion (courtesy of the ever helpful Hamtramck Registry website). If anyone has a '71 with the A07 code, it'd be great if you could chime in and report whether your car's equipment is (in)consistent with that "A/C special" option list. That includes @Autoengineer and @71Polara383. AFAIK, with the possible exception of the rim-blow steering wheel on one car (but not the other), the two coupes I mentioned have everything consistent with the list, and the outstanding shape of their underbodies despite spending much of their lives in the rust belt suggests that the undercoating was useful.* *: Interestingly, to be correct, cars thus equipped would need to have white sidewall tires. That's gonna be a problem for the owners of the two T-code coupes I mentioned above.
