Probably last two digits in the engine code. Example; x75 meaning 440 automatic transmission, no a/c, no power steering, power brakes, standard fan and no cruise control.
#526 = 273 x 2bbl, auto, no power brakes/steering, standard fan and no C.A.P. Engine code for this on the order sheet was 30. On the buildsheet it had #30 for engine but on the same sheet #526 so they knew exactly what was added or deleted on the engine before final assembly.
