Frank, the pod filters are approx 6 inches long right, so take a look at the bike and picture cutting away at least 6 inches of the airbox...
Jaeger, the NARK and FREAK are different, never seen the NARK, but I know the airboxes are quite different. Aside from a carb support bracket, it also supports the side covers, the fuse box, etc, and there's a second "bracket" that's more like a mud flap. So there is a little more to it... but yeah it would be easiy to make one too.
