I didn't get them directly from Tim, but through a dealer. Who couldn't have possibly misplaced the screws, the pickups arrived to him in their sealed box. I wrote him twice, CC-ing Tim, who hasn't provided any input so far. The dealer promised to fix this, but hasn't done so, in a week.
I hate pointing fingers, I'm just disappointed and seriously considering returning the pickups and asking for a refund.
Just checked my email again. I only CC-ed Tim the first time I contacted the dealer, the rest of the mails were only between me and the dealer. No reply from BK, though.
