I have a question on the difference between two of the Skybolt cowl fastening products for the Van's RV-9.
Specifically, I want to install Skybolt 1/4 turn fasteners all the way around the firewall, and plan to use the Van's Piano hinges along the horizontal split line of the cowl.
I'm confused between two of the Skybolt kits. The "complete firewall" kit has 4 less fasteners than the "Upper (FW/Side)" kit. The two kits have the same type hardware.
Which kit do I need, to get all the way around the firewall, including the curved top, both sides and under the lower cowl? I don't understand why the one labeled "Complete Firewall" has less fasteners than the other....
Ref: RV679J-C1P-F = "Complete Firewall Kit" 32 fasteners
RV679J-C1P-U = "Upper (FW/Side) Kit 36 Fasteners
