I’ve actually thought about modding mine like that. I have a Rod Bowers setup so I have a removable scoop. I would just have to glass a flange on and split it accordingly.
That looks like what I want to do. I’m using a Cold Air Sump engine on this install and being able to mount the air filter with half the cowl off would make things a lot easier.
Any photos of the inside or how you made the seam?
