These guys make a full set of hoses for the 3200gt and they can be made to look stock (black matte without branding).
We've used them on a friend's 3200 and the quality and service was good.
Maybe they would be interested on making a set for the Ghibli II/QP4 platform.
I'm not affiliated to them in any way btw.
