That is a completely different swing arm. At least from what is on my 09 C-5. That has different ends on the pivot tube. Those black disks on the end appear to be grease retainers, and not thrust washers. Very similar to what you might see on a Honda CB.
It's a different frame; I wouldn't be a bit surprised if your swing arm was different. But
completely different? Why not, I guess...
Re. the discs: interesting, considering that when I dismantled it, there wasn't any grease to speak of behind them, or on any of the swing arm pivot parts. But from what I read here, it's apparently not all that uncommon to find things inadequately lubricated from the factory. My swing arm pivot is greased now...
