Hey Guys I am getting ready to have my OME caster bushings installed by a local machine shop (i will be bringing them the control arms off of the truck) and i am trying to mark them per the supplied instructions. My question is this, per this picture below, is the horizontal line they are referring to using the rear bolt as the center axis and running a "Level" (using a bubble level) line to the front, or are they referring to a line between the center of the rear bolt and top of the bushing (regardless of its level relationship to the ground) as shown in the pic below. I am kind of confused here, the housing seems to be in the way to get a real accurate measurement What did you guys do? I know this is a stupid question and i am just misunderstanding the instructions i think. I just want to make sure i get it right!
