G8 -vs- GTO -vs- Holden Commodore -suspension(air ride related)

[PontiacDan]

I am considering going with an air ride suspension, but I need to know if the spindles from the GT0 will interchange with the G8. I've found a kit listed for 2004-2006 GTO, Holden Commodore & UTe. I am just wondering if this will work for the G8.

Here is a link, although there is little information about it:

Thanks again,
