https://fas.org/man/dod-101/sys/land/m8-ags.htm as to how many M8's the Army was looking to produce when the order was placed in 1996 in our timeline
The FMC XM8 was designed to combine a tank's firepower with a highly mobile, air-droppable vehicle. AGS was intended to be the Army's new combat vehicle, but in the form of a highly deployable, light-weight vehicle, with high fire-power and reconfigurable armor protection. The AGS was intended to replace the M551A1 Sheridan in the 82nd Airborne Division, and was expected to replace TOW-equipped HMMWVs in the 2nd Armored Cavalry Regiment (Light). A total of 237 systems were planned for procurement. The cancellation of the M8 Armored Gun System left the US Army airborne forces dangerously low on firepower.
The total program cost, including development, was estimated to be $1.3 billion. The Army had planned to procure 26 low-rate initial production vehicles with 1996 funding of $142.8 million
