3rd row seat hinge spring missing?

[b85chevy]

Hello, we have a rattle in the third row of our Yukon XL that seems to be coming from the passenger side/40% split side inboard frame hinge. There is a lot of play in the inboard hinge and it appears that it is due to a missing spring. Can someone confirm if there should be a spring on the inboard side of the passenger/40% split side third row? If so, any idea what part number? Thank you.

If someone could take a picture under the 40% side of the third row, that would be very helpful.

My 40% seat has no springs at all.but is also a manual open and close seat,no power.Maybe the one spring is an assist for the power fold?

I appreciate you taking time to look, mine is power fold.
