The only issue with the Pillars is that it has to me done a certain way as far as the side that is close to the glass. i want it to be flush, and not hitting the glass though. i think the only way you can do it to get the right angle is to see it in the car. Both sides are different (which I hate) but I had to do it that way because one hides the main AC tube for the rear AC system.
See how it angles weird. When its off the car though you don't see this. Maybe its just me though.
Here is the other side. You can clearly see they are different. Basically the drivers side had to have longer rods in order to be matched with the passenger side.
