Hello, I'm looking into purchasing a 2019-2021 Ford Transit but am unable to find one nearby with the second row bench seats. I need the middle seat for my newborn's car seat being that it's the safest seat in the vehicle. My question is, how labor intensive is the process of replacing the bucket seat with bench seats? Are the mounting holes already there under the carpet? Here's some pictures of the two that I'm looking at. Thanks ahead of time!
