This aircond was a bit of a squeeze to get it in a HQ,not sure if there is more room in HJs to WBs i had it mounted and checked to see if the console would fit and it didnt so i had to move the air cond a bit . As i said it is 600mm long but you can buy one that is only 400mm long and i also had to make my glovebox a bit shorter but that didnt worry me because it will only have a stereo in it.there are probably things i have overlooked and if i find any problems i will let you know.
