Hope this helps someone who has a similar rocket box/legacy/outback
> problem. If anyone has some comments, post them here.
I redrilled the holes on my Thule box...and then found I'd missed by about an inch and took it to the local rack expert who did it just about perfectly for $20.
I haven't experienced any problems from mounting it much further forward...I was tired of the tailgate not going all the way up as well.
