Harness height question

[omgcupcake]

DS is 2 years old and approx. 40" tall, 37 pounds and FFing in a Graco MyRide65. He is at the highest shoulder strap slots- TALL TALL TALL baby! My husband and I are separated, and I finally got sick of moving the carseat back and forth all the time, so I just got a new seat. It's a Britax Frontier. I want to get it all set up and in my car before Monday when I go get DS, but I'm just wondering which shoulder strap slots he is likely to need to be at? Is there anything else that I should know about this seat?

The harness straps should be at the lowest slot that is still at or above the child's shoulders. The MyRide top harness height is about 16.5", which is the measurement of the 6th from the bottom Frontier harness height. So I'm guessing he'll need it at the 6th or 7th harness position (or, if you're counting from the top, 4th or 5th position).
