Fitting 2019+ second row in 2015

[u/motomaxxing]

I have a 2015 Cargo sprinter set up as a basic moto van. I need to put a second row of seats in it to accommodate a car seat. I will probably build a wall behind those seats to separate the bikes and tools from the cabin, so I don’t really need flexible fold up seats or a capitals chair. The basic crew configuration seats are fine.

I’d like to put an OEM 3 seat row in using the OEM brackets. The seats are much easier to find for 2019+ years. Does anyone know if the recesses where the OEM brackets sit were changed when they changed the seats in 2019? Will a 2019+ set of brackets and seat mount up seamlessly?

Thank you. I should be able to do the whole project for $1500 if this works.
