It isn't readily available for old 60s musclecars either, only a few people have access to the information, it isn't public knowledge. Galen Govier used to do it for the old mopars, not many others can.
Dodge/chrysler just doesn't release that info, especially not on newer cars. You have to be content that the PCP car was a limited production color, only available on srt8's and classics, and only for a short time. In most cases the high impact colors were all built within a 30 to 45 day time window, then shipped out to dealers or those that ordered them early.
For instance, I know that they made 1188 DY cars, mines one of 596 R/T's and around 357 Auto's built. (auto R/T) But can't get the breakdown on how many had the HID's, Nav, SGII, Interior convenience group, etc. Pretty sure it was alot less than the total auto r/t's built. I'm happy enough with that. Know its rare, kind of obvious when i'm one of two r/t classics i know of in town, (know of 2 other srt8's) and i'm the only one with a TA hood. And to my knowledge its the only DY R/T that has a Tan leather interior in it. (katzkins ordered through dodge at time of purchase)
Also, On my 69 charger r/t se, i know it was one of 4600 built in 69, I know the build date off of the build sheet and its one of the first few to roll off the line, (built on sept 4th 1968) and from the charger registry know its the only Y3 creme yellow rt/se known to exist that came from the factory with a tan vinyl top/tan leather interior. Its loaded with options, many of which were rare...like the passenger side mirror that was only ordered on 57 cars, but i have no idea how many other Y3 charger r/t special editions were made like mine. Never seen another in 37 years, that alone tells me its unique. I really don't need to know its one of a kind, i'd still keep it like i have since 78.
