The motor mounts did not have material where it was needed, so I cut some 1/4" plywood and hysoled it in place, when dry I painted to match the rest of the interior.
I used a paper 1:1 drawing of my rabbit (see attachment) as it was mounted in my Flash at the time I was fitting up the Viper. I had to remove material from the inside center of the air inlet box to move the Turbine as far forward as my pipe length would allow. I included a full size pdf template for the motor mount add on pieces.
