I have a used set of Samson slip on duels that came off a 1999 electra glide. Should fit most models, but please double check. They are in good shape, however they do have some small spots of rust on the bottom of can, hardly noticeable. $125 shipped.
http://www.samsonusa.com/M-144.html I think what you have is the rolled thunder series. I have a set of ovals on my EGC and they sound pretty good. Thats a good price as well considering if you buy the new your looking at $500. Good luck with the sale.
I think that's what they are as well but wasn't sure so I didn't want to claim them and be wrong. Your right it is a smokin deal as I'm just trying to get cash to go on ride with my brother before he leaves for Japan next month. Only couple weeks til the ride...
