Yamaha DTXpress/DTXplorer/DTXtreme

Hello all,
  Quick question about the original DTXpress Drum rack(Not the II or 
III). I have read that it came fully assembled and apparently there 
are no instruction for it. I Just picked one up, so I can play while 
my son sleeps, and I believe that it is missing a couple of pieces. 
I've tried looking at the pictures here and on othere sights but its 
hard to tell. Does anyone know how many pieces their should be. I'm 
speaking of the bars. It seems that everything else is here. And has 
anyone found instructions for this??? figured I'd ask again. 

Thanks in advance
