Began fitting and trimming the rear cooling baffle. I used both poster board and some 3/8" plywood to work out the contour to match the inside of the cowl. Once I got close, the cowl was installed and I reached in thru the oil door and under the sides of the top cowl to mark a final trim line giving a 3/8" to 1/2" gap.
After trimming the rear baffle I did trial fitting of both the port and starboard side aft baffle components.
