HAHA thats awesome.
Well not really a cool find but the other day I was working on the 240z 72' and there was a bird behind the gastank eeeeek! Dropped to the floor and bounced back and forth, must have been there along time..
Best place depends if theres someone local to you so you can check it out in person rather than have something shipped. If thats not an option then you're best bet is to do some searching like previously posted.
