Update:
I was informed that I received the right parts but trimming will be necessary. This is because of variability in different builds. I noted the Rv8 on the website has a slightly different canopy outline than mine. I used Vans canopy circa 2010. The plane on their website I assume used the aftermarket canopy that is/was available a number of years ago. Either way, there will be substantial trimming necessary. Enough that the back piece will not even fit against the canopy to measure. I will need to make a template and start cutting. Might as well have sold me a single square cheaper than a ‘custom cut’ option. The magnitude of this problem may be related to the rv8 canopy vs more traditional patterns, but definitely more installation than implied. Not sure I would have dropped 1 grand on them otherwise. The email suggested the ball is in my court as far as returns go. Kinda feel like in for a penny, in for a pound now.
