Here's what I substituted:
Beringer Wheels & Brakes - If you ask them, they will give you a list of things to delete from fuselage and finish kit. I sent that list to Vans.
Control Approach Pedals - Also will provide a list of things to delete. I sent their list to Vans also.
Flap Actuator - Replacing with PH Aviation
Right & Left Read Windows - Cee Bailey's
Fuel Valve - Will be substituting with Andair. I want to order from Vans, but they only carry FS2020 valves, which Andair's website says is only suitable for up to 200hp engines. Not sure what I'm going to do yet, kicking that decision down the road.
Ordered oil cooler mount, ducts and static air kit because I heard that's the thing to do on Fuse instead of FWF.
