Where to get boots for rear air shocks?

Does anyone know a way to obtain a pair of replacement rubber boots for the rear airshocks on my '82 kz750-n1 spectre? It looks like where I look, they have nothing. Any help would be nice, because mine finally completely came off and the bright bare metal looks goofy

Have you tried Babbitts Sports Center ( www.babbittsonline.com/ ) they have them listed as part number 49006 at $26.12. Don't know if that's each or for the pair. They have a 'Call Us' marked beside them instead of 'add to cart' so they may be on back order. Hope this helps.
