Installed the rollover stiffening IAW the manual Section 9B. A 6 BID layup was applied inside the top of the rollover. The bottom 2 BID is 14" long. The next 2 BID is 12" long and the last is 10"long. 1/4" foam was then bonded on top with runny micro and let cure. Lastly, a 4 UNI layup was applied on top of the foam. The stiffener is now, theoretically, custom fit to the fuselage.
