Precise production numbers for specific Camaro options like the 1992 5.0L TPI V8 with G92 (5-speed) are not readily available from public sources like GM's archives or publicly accessible production records. These details are usually considered proprietary information.
To find this data, you would likely need to access internal GM documentation, which is not publicly available. Even then, the level of detail down to that specific option combination might not be tracked.
