Fresh Air Vent Cables

[440six]

Hi Guys, I have a question regarding the fresh air vent cables for a 71 cuda. I have seen some with the round knobs and some with the square knob with vent scribbed into it. Which is correct for a 71 cuda. I always thought that the round knobs were on all Challengers and only on the cuda convertibles, but I think I might be wrong. Any experts out there want to help clear this up for me.

Thanks

My 1971 Barracuda convertible has round knobs.

The square knob cables were used in 70 only round in all other years

Thanks guys for the info, to bad because the square ones look a lot better. When my car was restored way back, there must of been a 70 cuda parts car used, as my hood is a 70 model year as well.

I agree the square handles look better, just 1 more reason I like the 70 best
