I currently have 13 left (multi item discount with higher numbers) , and I might have more in the future.  They are new and unused they have a little scratching from hitting each other.  It's random and noticeable in the pictures.  Great custom design to make your work look amazing.

  There are mounting holes for easy installation and alignment pins.  Alignment pins can be ground down if needed for flat surface installation or utilized for bed alignment. 

Unique tail design allows the heat sink to hang over the edge of the mounting surface.
