The rubber bumpers(all 74 1/2 year cars; had to be good for 5mph impact) started at 18320 to 18950 with the 4spd tm. before they started putting in the 5spd Gettrag. (we refer to these as 74 3/4, which is just before the '75s with all the pollution stuff, air pump, injectors, etc.).
These numbers are actually listed in the PARTS manual.
