This 1/4" Steel Laser Cut & CNC Formed bracket bolts to the front RH side of your AAZ/AHU (and other similar blocks including some gas motors such as the 058). You can build your motor mount off of it.
 
Hardware included. Fits AAZ and AHU engines, as well as some gas engines, and probably many others.
 
This is only the RH plate. You'll have to fab the LH side yourself.
