I have 1987 panels that mey fitIf you are talking the side covers as in number plates/side cover... only 1986 will fit. 1987 is different, then 1988 is totally different.
Believe me... I have been looking for a while since I had an original new 1986 that was purchased in late 1985 (I know... showing my age) and have been looking for one for a while now. I recently picked up a 1987 and allot of the mechanicals are the same as the '86 but side panels are different. I believe the seats, radiator cover, and tank as well as front fender and number plate are interchangeable with the '86. I believe the bloke above who said Dennis Kirk is correct that they have them. They are a solid color and you may need to paint, stick backings on to make look original but they should have them.
Hope this helps,
