need 4-runner help

we need to convert my sister's 2004 4runner to a third row. i know this isn't strictly tacoma-related, but with their similarities i had hoped someone had experience with them. i've done this swap before on a durango and it was pretty straight forward. just needed the seats, seatbelts with buckles, and the trim to make everything look factory. would this swap be pretty much the same? what about the second row seats? do they fold differently in 4runners equipped with third row from the factory? or would it be the same? any guidance would be appriciated. thanks!
