The ebay item is located in Florida.  I would guess that he got it off an 04'.   either way it looks like it will work. 

I'd buy it. then again it isn't my $20.

That ebay rotor would work fine...but you need to check shipping/handling. The people selling Commodore 64's seem to think $20+ for handling is resonable and customary.

I think those people should be wearing RF anklets when convicted.
Screw it, use bullets 

Regarding it as 03, it may have been a Canadian bike, but not certain. He could have been looking at the manufacturer date on the VIN for an 04 USA bike also.  The engine codes don't usually have a date string.

If we look in the Suz OEM service manual, they have region codes that essentially tell you if a bike was available in a market.
<<EDIT>>

The schematic "P" codes for the various 2003 models are:
P-02 UK, P-19 EU, P-24 Austrailia, P-28 Canada, P-54 Spain

Cool thanks. I went ahead and bought it.

He is also selling the cover that I might need.

But the cover is for a 1993. I checked bikebandit and the 2004 cover and 93 cover are different part numbers. Can I safely assume that to mean the 1993 cover won't work on an 04?

Thanks again everybody for your help with this. I had built it up in my head to be much more difficult especially after going to the dealer and not being able to communicate properly what I needed with them.

And thanks to leo I discovered the different ignition system setup used in the 04 and later GS500F that uses only one coil in the signal generator instead of two.  Couldn't figure how the 2nd cylinder got a spark signal 180 crank degrees after the first with the one pickup coil and one large trigger lug on the rotor and wondered what the other five smaller lugs were for.  Found the 04 wiring diagram and searched in vain for a crank position sensor that might provide the necessary input.  After  further searches I found this posted by LimsXray last Sept:

<<<'04+ are a little more modern in that the ICM knows where the crank is in its rotation at any given time, thus allowing for more flexibility and precision in its ignition control.  On these models, there is a wheel with multiple teeth, all the teeth being alike except for one which is larger than the rest.  There is also only a single VR sensor.  The ICM is able to distinguish between the large tooth and the other teeth.  The large tooth acts as a referance point to a certain point in the cranks position, while the other teeth act as 'pace marks'.>>>

All is clear now and my headache is going away.

Although I think it will, I wouldn't know from experience if that Crank case cover will work on an 04'+ GS,  But the little signal Generator cover WILL fit. 

I bought one for my 01' engine.  see pic
I stripped that black paint off of it.  see pic

If you do go with changing out the Crank case cover, it isn't that hard to do. 

Cool thanks.
