No 1st gens (99-02) are different than the 2 gens (04+). 03 is a "2 gen" but it is considered an odd ball year as some of the parts aren't compatible with later models. They can be made to fit all years with special kits which include customized spacers.
03= silver wheel 04= silver wheel So you want a 05+ SV (05, 06, 07, 08 or 09) 2010 weren't sent the states. I'm not sure if a gladius wheel would fit either.
All rear sv wheels are same. Difference between 1st gen and 2nd gen wheel is in bearings and spacers. If you use bearings and spacers from gen bike you have all this wheels will work.
