How do you remove the backseat

[JAMAS]

And I still do not have it

Unfortunately you were right. The bolts are on backorder (3-6 weeks).

The front facing (big) bolts are good, but one of the rear facing (small) bolts is broke. Are the small bolts just to ensure the seat doesnt fly forward when they are folded forward? In other words, should I be concerned that one of the small bolts is missing when I latch in a child seat?

is probably okay for awhile but get it as soon as you can or get a stand in at the local hardware store using the one you do have as a sample
