DRZ Drz 125 rear shock

I am curious if anyone could tell me the size of a 2003 drz125 rear shock? Or what other brands bolt right up with no mods.
Yes i have googled and googled with no luck of my question.
 
Thank you!!
I bought a drz125 with a bad shock for a good price. I found a oem for 400 plus change. I've searched the bike and shock nothing really shows on google. So I figured if anything like my atv I could find the size in mm or inches of the shock an search for one by the size
