I think maybe some of the utes, XH or so were 4P lockers? My centre was $250 off a VR or VS sedan from memory (car written off brand new).
4P was an option listed as early as XR commercials but with an open centre. The later ute ones I've seen had a chunkier, tougher housing.
The whole Centura swap is past its time. Definitely one thing I would recommend against.
