Mike, I got these numbers from Chrysler Historical in 1986:
9,862 440 automatic hardtops, 362 automatic converts
4,004 440 4 speed hardtops, 178 4 speed converts
14,406 Total
The numbers on the Hemi cars were mixed up. It looks like 98 426 automatics, (I think 98 but not clear?) 4 speeds with 6 automatic converts and 5 4 speed converts
On a side note, they reported (15) 440 RoadRunner automatic converts!!, no 4 speeds and no A12 converts. This was in their writing on a spread sheet I mailed to them asking for production figures on RR's and GTX's from 67-71
