XS29x8B279428 spd 205 (2/5/68) & 4-speed trans assembly date 1/9/68 (440 or HEMI Charger R/T - if the trans has always been an 18-spline)
XS29J8B357735 spd 424 (4/24/68) & 4-speed trans assembly date 1/9/68
RS23J8G225124 spd 424 (4/24/68)
The Chargers were assmbled at Hamtramck - the GTX at St. Louis, but it is a simple example that "first in - first out" practices were NOT in use at the assembly plants. 11 weeks & just short of 80,000 cars were built at Hamtramck between the use of 2 transmissions built on the same day (44 units apart).
