Part identification help

[jcrumpley]

In doing the inventory for my IRS I found what I think is a problem. In the photo I have three identical pieces and one different one. I believe I should have two of each. Can anyone tell me what the part is where I just have one? I think it is either 16239 or 15857.

These go on the upper control arm out at the wheel end. My guess is you should have 2 of each but don't have a car in front of me to confirm.

My 2015 IRS does have 2 each.

As others said, you should have two of each. They go on the UCA to spindle attachment. Those parts were changed during my build, and Factory Five sent me an update package. This picture shows the updated parts you should have received in your kit:

Look like this when installed. You can't see the inner half obviously.

Thanks everyone. I'll call factory five tomorrow. I had a few other missing parts as well in addition to the ones they had already noted on the back order list.
