All right, so I scrapped my original airbox plan and did something that fit a little better.
a 90deg 1.5" barbed fitting.

cut off the threads

sand off the barbs

and glue into the plexiglass(everything is unglued right now for fitment)

I used a fernco 1.5"-1.5" elbow on the cvt intake


Here is the the CVT intake, exhaust and left side airbox fitting hoses

and here is the only way I could figure out how to route the right side of the airbox hose.

That's all I got done today. I plan on wrapping all the hoses in foil tape to protect it from heat.
