GSXR 600 rear shock with the horizontal, not kicked up reservoir bolts in. I think it's an 06-07 IIRC. Everything is documented in here somewhere, TurboFB did it IIRC.
By bolt-in I mean: you'll have to space out the dogbones and move the coolant reservoir (do not delete, you need the thing). If the bike was used for any length of time, I would also consider getting the fluid and gas refreshed. The stock fluid is passable at best and is DIY possible. You'll have to bring it in for a re-gas though unless you have access to a nitrogen tank.
If you're lucky and diligent, search for a race-prep take off and just run the thing and rebuild it later, it's what I did (and re-did).
Be warned though, as soon as you do this you will find out just how bad the stock forks are. It's like a gateway drug: start budgeting for springs, oil, seals and emulators now. Brakes are next...
