Focus MK2 roof rack slats

[FordAlan]

I recently fitted a second hand roof rack to my Focus, i removed the previous roof trim panels / slats (x4) which are the generic trims.I did notice that on a video i watched to make sure i was doing it correctly, the technician did use a different form of roof trim which seemed to be for the usage of roof racks - But i don't have any to hand? Are these items easily obtained or would you pay through the nose to acquire them?

The only reason i ask is that with my thule roof rack, there is "gaps" where i am worried that water could seep in to the gaps, while the sealant is still present it also presents a risk of rust. Also add to the fact that any type of speed causes the wind to whistle in the cabin.

Many thanks!

I don't know if they're available separately, but to be honest, they don't really do much - just help line up the bolt
