Used the stock hardware with a few bells and whistles left over from my WH Edge 540T (the plastic surrounds on the screw heads and the aluminum stand-offs on the pull-pull). The DL is awesome!! Got the fuel up in the lines and two flips with the choke on and it popped. Two more flips and it purred like a kitten. Transition is instantaneous as is the power. I'm gonna love flying this bird!
