Racer X Rear Set backs

[neweuser]

Hey guys, I could use some help. Anyone who has set backs, I could use some pics on how to adjust the rear arms. I'm just not sure if they should be level all the way to the knuckles, or if it's ok that the height increases a tad.
So if anyone has some good pics on where to set the upper links and what not, that would way cool!!!!

Thanks a million!
