The SD R rear light is specific to the SD R and won't fit the standard bike. It comes with the solo kit and It's quite a nice shape with LEDs, but I can't see any way you could make it fit the standard SD. BTW, the solo kit is the same kit that is fitted to the SD R, with exception to the rear section which comes unpainted on the kit, It's not an aftermarket KTM part that has been made to look like it. There are two different part numbers though, one for '05/'06 bikes and one for '07. The difference is in the internal tray where the fuses and relays sit, apparently they are different on the '07, but that's the only difference between the two kits.
