I hate to buy used off ebay cause I don't know what is compatible from year to year.
For the side fairings all years are interchangeable,as is the belly pan and the side covers (under the seat), and the tail piece.
The only fairing parts that are 86-93 or 94-06 specific are the fairing cowl, and all inner fairing parts.
On the side fairings the 86 and some 87s had screws that attached the "main vent" (see attached pic) but otherwise they mount to the bike the same.
