Yamaha DTXpress/DTXplorer/DTXtreme

I thought the DTXprss kits use a KP60 or KP65? I looked in my manual 
and I can't see.
This KP80 has Yahama letters written sideways vertically in the back 
and the back is covered all the way from top to bottom, where as my 
DTXpree I kit have just the Yamaha logo at the top rear, and the 
back is covered only at the top where the Logo is..

I ask because I'm looking at buying a spare.

Thanks, Steve
