two-stage bolt was bent, and I finished it off trying to straighten it. I have a CT-2 parts bike, but it appears that this upper shock/muffler bolt on the AT1-E is longer outside of the frame than the CT-2. This is due to the muffler being mounted to the shock bolt on the AT-1E but tucked up under the seat and mounted to the frame on the CT-2. Am I right so far.
I went to Partzilla. They have the muffler side upper shock mounting stud for the AT-1E; so sayeth the schematic. But when I clicked on it, the picture shows the LOWER shock mounting bolt, both sides of which are the same:

That's not what I need, and everything else is "Unavailable." Anyone have a valid part number? Anyone have what I need? I'd gladly trade you the shorter CT-2 stud for the longer AT-1E stud.

The actual Yamaha parts site will not work for me.

I just had a quick look on CMSNL and I think the part you're after is 248-22241-00

Thanks. I believe you are right, but unless it's been renumbered, supersceded by another number, that number doesn't even appear on the Partzilla charts...
What do you suppose they'd want for freight for that little number...

With the proper part number, I got one off ebay for $10US, and another $7US shipping. Not cheap, but it'll MAY get here quicker...
