Yes, it should be possible. I fitted the exact same seats in the picture to my previous model (169) 4x4 and it was pretty straightforward. As mentioned above, one or two of the runner mounts will need reorientation (drill out the rivets and swap the brackets over), but otherwise it should be OK. The Abarth seats are very comfortable and a significant improvement in my experience. My previous car was red so these particular Abarth seats worked well. I changed the rear seats too, which were a straight swap and very easy.
I would do it again too, were it not for the fact that my current model 4x4 has a nicely coordinated green interior and I don't think Abarth seats come in a suitable complimentary colour. Black would still look odd and spoil the otherwise brilliant current car interior in my view.
