What is the Tamiya kit number for this?

Has anyone built this kit before?

I need to order the parts tree in the pic from Tamiya but I'm not sure which it is.
The instructions say the part I need from it (hood scoop) is on the C tree. But when I zoom in on the tree itself it looks like the letter B down there.

Also if someone could give me the kit number it would really be appreciated.

Thanks

The kit number is 24231, it should say that on the box actually.
