Re the XC ute seat. No, its got no, um, arse in the seat.
There are no passengers in the back of an XC ute, so no ash tray or vinal cover.

Good news is after you put a 65 dollar bench seat cover on it, your sedan gains another 3 inches of usable knee room in the XC sedan when an XC ute seat is used. Trust me. I sit in the back of my XC all the time!
Oh, and the XC runs the Coupe roof line, so the seat height may vary a little becasue of the spacers used. It certainly did in the XF sedans and utes.
The whole bench and runner mechanism must be matched.
Some of the runners between the XA to XF Falcons have small variations to the stupid M8 tappered bolts, and you can't swap the runners over.
I tried to put the XE ute seat runners on my XC sedan seat, and now I have two broken seats because although the seat to floor bolt pattern is the same, the little half assed bolts which hold the seat frame to the cushin have different bolt spacings.
