A999 torque converter hub size

Chrysler started using 999's behind the 360 2 barrel engine in 74. In 78 the lockup came out but not all 78's were lockup. Then after that the 999 was used in a hit and miss situation. The Diplomat and Fury cop cars used the 727's early and then switched to 999's. They used the 999 in some light duty pickups and full size vans.
