Reinforced lower control arms vs. upgraded/tubular lower control arms?

a friend just put the entire set up in his charger.. said they he needed to use the QA1 sway bar. wasn't sure if he was mistaken or not.

Yeah, in that picture of the QA1's the sway bar tab looks too far in to use a factory swaybar.
Here's a pic of my lower arm with factory swaybar. You can see the tab is clear out past where the shock mounts.
