Seats are in - see pics. My oldest is 7 and shouldn't have any trouble squeezing through. It's about a 10 inch space (tough to balance the tape measure for the pics). I have a harness bar in, but it comes out in about 20 mins.

As others have said, they're very comfortable. DE day tomorrow...

 

other side...

 

Very nice installation!

Congrats!

 

Thanks for the pics. It looks tight back there...too tight to get to a rear car seat.

Did you use the GT3 side brackets with the stock seat rails?

 

It is tight - but works fine with a booster car seat. It would be tough to do an infant/toddler car seat especially if you had to reach back there to fasten the buckles.

Stock seat rails, GT3 side brackets.

I'm going to take the harness bar out in a few weeks and will post a pic with the two booster car seats back there.

They felt much much better on the track today than the stock seats.
