Give them a call. They don't have a kit. They can make one up but you need to leave the vehicle with them so they can get the hoses and fittings correct. I suppose they have to draw a line as to what they carry, and with so many people building custom rigs, maybe the bulk market isn't there. As as example, you can still buy a portal Kit from them for a GQ, but they will resist selling it as it has not undergone second stage manufacturing testing and verification. The GU diff housings are the platform, and we all know they fit the GQ. I was unable to find a VASS engineer in Vic who would take on this testing when I looked at it 5 yrs ago, and shortly afterwards Marks dropped the GQ listing.
