When I did some research on the topic I found the following:
There were 32,368 RM21 cars made in 1969.
31,397 were 383CI 335HP cars
650 had the 440CI 6pak
356 had the 426CI Hemi.
There were 46,847 RM23 cars made
45,629 were 383
797 were 440
421 were 426
There were 1,890 RM27 cars made
Of which 1,880 were 383
No 440 cars were produced in a convertible
And 10 426Hemi cars of which 6 were automatic and 4 were manual.
Where I found the data they did document the number of manual transmission cars in both RM21 & RM23, but I didn't write it down, to lazy to look again. But it is out there. The purpose of my research was more for the Convertible option, which is what I have.
How many N96 / R4 you won't find any data, that I'm aware.
There were 80,914 Roadrunner made in total.
I found various sources with different numbers though, but these seem to be the most consistent. But I think 69HemiBeep is correct when he says there are no real source's at least directly from Chrysler.
