The radio box can be installed either in front of or behind the engine, you just have to build one to fit your location. As far as the pipe, that's kind of up to you on how you want to route and secure it. Since I used a NR 21 5 port, it's probably going to be different than your set up considering I had Glenn Quarles rework my carb so that the throttle is on the right side rather than the left
