Do VX/VY front swaybar interchange with VZ

[Surfwagon]

I have access to a Whiteline VX2 front adjustable swaybar and was wondering if anybody has fitted or knows if it will fit to a VZ (both V8's).
The reason I ask is that Whiteline shows different part# for each model.
VX/VY #BHF14Z and the VZ #BHF61XZ.
Spoke to Whiteline and they say they are not interchangable but short of opening to boxes to check (no pics of VZ bar) they couldn't tell me what the actual difference was.
Thanks in advance.

How do you adjust a sway bar ? have never seen or herd of a adjustable sway bar befor thats all.

They have 4 holes where the link attaches so changes the distance between the end of the swing arms and the main part of the bar.
The further out it attaches the smaller the bar feels and the closer in the larger the bar feels.
