Bought on March 1 2010, Sorry I guess it has been more than a year.
I'm not sure what I'd end up with if I rebuilt a final drive

I got this a couple of years ago for around $350... I put the final drive
on my buddy Henry's bike not long after I got it, so I don't have such
an awesome spare any more...

I saw that there was a trike shop out on the hiway near where I work...
I stopped in there, seems like a two or three guy operation... one of the
guys has a Valkyrie, they didn't have any Valkyrie rear-ends, but they knew
that good Valkyrie stuff had value...
