I inventoried the firewall forward kit. There are lots of cool things in this one, but hard to see $5000 worth of parts in here! The only kit deletions I made were the Alternator and the exhaust system. I'm going with a cold air induction sump which is incompatible with the Van's exhaust so I ordered direct from Vettermans and my engine supplier will provide a Plane Power 60 AMP Alternator to me. The only missing item was an AN 8D elbow fitting.
