I'm having serious problems installing a child car seat in the 2nd row bucket seats of an 04 Nissan Quest. the child seat is flat at the base, but the bucket seat is curved at the back, which doesn't give a good fit between the 2. This creates a gap which prevents the two from fitting snugly. in turn, this prevents the seat belt, when connected, from holding the car seat tightly.
Is there some extra tether or kit I need to do this right? If so, you'd think the dealer would've told me this since I only mentioned a dozen times that I planned to put in 3 child car seats in it.
