64/65 Barracuda factory Options question

hello, I have a few questions regarding 65 Barracuda, maybe someone knows...

Did the 64 Barracuda come with a manual choke lever from factory?
What determined if the Barracuda had one or not?
I have an early 65 model, that has one mounted underneath the factory AC
this is a Commando 273 with 4 speed
I don't recall seeing this on other models I had, Formula S cars both 65 with automatics

Also, never found an answer on the Special Equipment Package #4060 listed for $29.35 on factory Chrysler Window Label on another 1965 Barracuda.

Does anyone know what that package was?

Finally, mine came with a factory front sway bar, but is not a Formula S.
On the Purchase Agreement, it list the Commando Engine for 99.40, but it was not noted that it had the Performance Group Package. (which would have been for a higher amount if listed, as it would have included the Power Brakes and suspension package, if not mistaken)

It does have factory Sure Grip, Power Brakes, 4-speed.

Unfortunately, I do not have a window label for my Barracuda.
I do have the Original Purchase Agreement dated September 25, 1964
Curiously, it is noted in parenthesis (NO STICKER) underscored handwritten)

I also have the Certicard and Original Invoice dated Nov 16 1964 when it was taken delivery

thank you!
