Technical help

I just won a set of TT front seats and cupra rears (both half leather for £100) for the Monte Carlo (the wifes face was a picture, at least the garage is warm so I can sleep in there), the technical question is will the rears be a fairly easy swap? The TT fronts are still on the Audi frames so not sure if I will have to swap the frame over to the Fabia one but I have a pet sparky to configure the wires for me. I don't have the seats at the minute so hence the questions.
