Question Throttle Plate ID for a 7040273

Hey Guys I was wondering if someone could help me ID this throttle body assy and the levers. I'm pretty sure it is original to my 7040273 carb but just wanted to be sure.

The casting is 7037174 which I think is correct however it was also used on other quadrajets of the era so that is only a clue. Hopefully it will have some other features that someone could use to confirm it's the correct throttle body assy.

My other question was about the primary throttle shaft/levers. Which one would be correct for this carb? The one that is installed is the one that I believe to be correct. If you look closely at the small levers on the choke side, you will see that it is more pointed that the one that is not installed. Also, the radius of this one where the plates attach in the bore is quite sharp where as the one (green one) that is not installed has an obvious radius. Not that this radius should matter but it might help to ID the correct one.

Any help is appreciated as I'm about to rebuild this carb and want to have it as correct as possible.
