I don't like your chances
The cabin at shoulder level is only 1250mm wide.
If those seats are 610mm wide, then they will be near as dammit touching the doors and each other
The other dimensions are reasonable.
I have Skyline seats in my B120 and they are snug enough.
They are 510mm at their widest point, just above the waist line.
Another limitation when fitting modern seats to the Ute is the fore aft adjustment.
You may find that even with the seat firmly against the rear panel you will still be sitting up like Jacky with the steering wheel close to your bod.
If the seat has minimum padding then that problem diminishes a little.
