Thanks Sandy. I'll ask about the true condition. I'll probably just order a new one unless this one is perfect, which I doubt by the description.
I need to get myself something for my upcoming birthday(from the wife). If I don't, she'll get me something I probably can't use anyway. I'm at that point where I'm really hard to buy for I guess. So in a way, an NOS one won't cost me anything. It's still not about the $, it's about keeping the bike as nice as I can. I actually prefer the modified version I cut. The NOS would just be used if the crack came back.
Thanks again for taking the time.

Keith, that ducktail wasn't put there just for looks. It added considerable rigidity to the chain guard.

I haven't noticed any difference as far as rigidity. There's a metal plate at the rear that seems to take care of that. I don't see how the ducktail makes it any stronger. Maybe it does but I still have no issues. I think the mass of the ducktail being "after" the crack would eventually open the crack again from vibration. It can't now and I like the look much better now. Thanks for the reply.
