For the what, ninth time? Yeah, it was—in Canada, where at least parts of this car were built. Go throw your eyes at the '66 CFPC pages I posted, earlier in this thread.
Yeah, the American one, which does not apply to the car in this thread.
The small clutch they used couldn't launch the car right with that high 1 st gear and would wear out in short order which is why they discontinued the 4 speed option for 6 cylinder for 1966.
Now you're just makin' stuff up as you go along. Or do you have some kind of evidence that the '64-'65 (US) '64-'66 (Canada) 6-cylinder/4-speed cars suffered problematic clutch wear? I'll bet a few six-packs you don't, 'cuz they didn't.
