The 66-67 clutch pedal is different than first gen, the brake pedal is the same only in 66. The 67 one has a bigger bend, a.k.a. the "swoosh", in it to clear the larger steering column. The repop manual brake pedal is based off the 67 one as it will fit 66, but not the other way around.
The cross-brace or hangers are 62 - 65, 66 and then 67.
There are other minor differences between the years with hardware. Does not always matter dependent on your application.
