The cowls are made up of two sides, a nose ring, and two plates that form the inside of the scoops. Fit was good, however to get them to fit on the nacelles a little trimming and tapering was needed
on the duct plates. There is no definite fit for the cowls to the nacelles except for the aft end of the air ducts so some planning is needed there. Don't leave any extra pour block on
the back of the engines.
