Tacoma 2nd Gen Access Cab Help Please

Hello Goose Gear fans,

We are looking for help in determining what model year that Toyota made a change to the Access Cab rear seats.

Here are photos of a 2008 Tacoma Access Cab

Here are photos of a 2012 Access Cab

If you will notice the rear section of the later model years has a bump out in the back wall.

If you know what years this transition took place we would greatly appreciate your help.

Thank you,

Brian
