I have looked on eBay a few times for them with little success on my specific year and model. how specific do I need to be? Will another year work or even a similar model? I am still trying to learn which models are similar enough to exchange accessories with my 1992 FLHS.
I have one of these. It's a little smaller than the Harley trunk, it's made of ABS, has a rack and it's only $200. It easily holds 2 full face helmets or a coule of 24 packs of cans. Here is a picture of it installed.
