I've been patiently waiting on my new swingarm that's on the way as we speak. It will be here Tuesday. I have done a bit of research and found that Jamis didn't change the design of the chainstays until 2006. Here are a few comparisons:
2005 XLT's little support webbing toward the dropout end of the chainstay is much shorter than the 2006 and 2007 chainstay. The yolk looks different too.
2006 XLT (the chainstay-yolk interface where mine broke, is welded transversely instead of just straight across)
Here's the funny thing...look at the Diablo freeride chainstays:
It's almost like they are using a Diablo swingarm for everything because of all of the warranty issues that they had to deal with, hehe. I called Jamis and asked about it and they said that the swingarm is very similar, but the Diablo has a little thicker tubing in spots and the yolk is a little different.
That's reassuring to me, knowing that I'll have a tougher swingarm this time.
