The seat base fits like it was made for it. The Barracuda seat back hinges mount in the same spot as the wagon hinges and the back moves just like on a Barracuda. If you look at the picture you can see on the passenger rear wheelwell where I've removed the wagon seat latch catch. I've still got to weld the Barracuda latches in the same spot and mock up will be done. I will carpet the entire back area and leave the seat back down like in the picture. It's just me and the wife and there'll be no cargo hauling in this wagon.
