help finding correct 03 speedy top yoke nut

[xactoman]

I am putting the final conversion pieces on my 2000 daytona to make it a speed triple. I recently got a top yoke and riser from an 03 speedy from ebay. Yoke fits just fine, but unfortunately the top yoke nut from the daytona is different from that of the 03 speedy yoke. The speedy nut appears to tighten into the yoke whereas the daytona nut rests on top of the yoke. (see photo of 03 speedy yoke) A quick search on bikebandit gives me 3 nuts to choose from, all listed by serial number. Here is where I need some help. If any of you can point me in the right direction for the top nut, I would appreciate it. Do the serial numbers match with a year?

Here are my options.
1. TOP NUT, YOKE SERIAL NUMBER 190357 AND HIGHER

2. TOPNUT, YOKE UPPER SERIAL NUMBER 172476 AND BELOW (PLUS 173398 TO 173815); 190356 AND BELOW

3. TOPNUT,YOKE UPPER SERIAL NUMBER 172477 AND HIGHER (EXCEPT 173398 TO 173815)

I am guessing that 172476 is the 2002 and older, 172477+ is the 03-05 and 190357 is the 06– current model.

Or if any of you with an 03 speedy can check your top yoke to see if it is like the one pictured and get me a serial number, I would appreciate it.

thanks,
