Default Upper control arm question

Hi everyone, I installed new AFE power Pfadt poly bushings in my C6 a while back. My car has been apart for awhile now. On the front upper control arms I installed the new bushings along with the pins. I can’t remember the orientation of the pins. The pins have a round hole and an oblong (elongated) hole. My question is: do the elongated holes go towards the front of the car, or towards the rear? Thanks in advance.

Maybe this will help. I just took a look at my control arms on my 2009 Z. I noticed the washers on the bushings are installed on the “outside” (facing wheel well), like the attached photo of the front passenger side of my car. From your photo it looks like you have some flipped backwards?

Please for the love of Christ, tell me that you marked/counted the amount of washers that needs to go behind each upper arm point when you pulled them off, or your alignment guy is going to have a lot of work cut out for him to add them in as needed for the alignment instead.

I've been working on mine; the original left/driver's front upper had a 'F' stamped on the left/forward end of one dogbone and 'R' stamped on the right/rearward one. I believe that corresponds with the smallest hole near 'F' and the largest/elongated hole nearest the 'R'.

If you look at the @Borg Motorsports
(at 26:50) Lane also says that the smallest hole is forward.
