Vt Sedan seats in a Vy ute, different heights.

[HSVjack]

Ok so, my dad has a HSV Manta, he removed stock interior and put pull leather coulson interior. I’ve got a Vy storm, wanted to put his stock seats in mine, everything lined up perfectly, except the ride height was just that bit to high up to be comfortable. So I’m other words, do sedan seats and ute seats sit at different heights, or is it a Vt to Vy thing?
