Oh, but I did :)
Quality stuff that fits on like it came from the factory (fits better than bits that actually did come out of the factory :P). Basically there's a rail that hooks on to the roof edge that's covered up by the rubber seal lining:
Easily tightened and aligned by the allen key screws:
Followed by the cover that's locked in by key. Really looks neat!
Pity about my shitty photo taking though. It's been raining a lot in Australia (especially for summer). Looks like the drought's breaking.
And... I'm selling the BBS wheels. I'm not saying who to, but he will definitely look after them very, very, very well. I'll miss them, but it's time to move on!
How's this for moving on?
