Once Chrysler accepted money from US government, the government more or less told them what to drop. The first thing they were told to drop was the big truck division (not a car line but the entire division).
The ’80 F-Body design was planned to stick around for at least a couple of years. Government told Chrysler like in April/May of 1980 (or so) to pull the plug. Production of them stopped almost immediately (didn’t even get to end of model year production). I remember the dealership I worked for saying they had a bunch of special order cars (Tulsa police department) that didn’t get built.
