I've used all 3....Zanotti, Chicago, and Lakeshore, and have NO complaints with any of 'em. They might all do it, but Jim Sparks (I think) @ Lakeshore will search dealer wide for a part if you cant wait.
Like you, Im going (sooner or later) to order fairing lowers....and everytime I do a price check....Lakeshore offers the lowest price, and with the order being over $500....it's free shipping.
