I wanted to purchase an OEM spoiler for my 2005 GL1800 through Wingstuff but was advised that Honda discontinued this particular spoiler. Candy Black Cherry (R287M) was manufactored for 04, 05 and 09 model wings. My question: Can I use a spoiler that is earmarked for a 2009 model wing and install it on my 2005 wing? What would be the differences between an 05 and 09 spoiler? Thank you in advance.
