dbair,

You again? :-) Seriously, from my experience, I would think that shortening the nose 1.5" would be a good starting point. That may screw up the cowl though. When I shortened mine 3", I built a new one. Half that distance may allow you to work with the kit supplied unit ... if you can stomack the plastic.

I put my hatch for the same purpose in the bottom. The flat surface is easier to deal with, and out of sight. The top would be a real pain to turn into a hatch.

Have fun!
