I must have missed that post. A quick glance at the parts page shows the RLCA and knuckle being the parts specific to the 2022. I suppose my idea was wrong. However with the only change in the RLCA being that the hole moved outboard 10mm, my shock is now where it would have been on the previous model.
After some digging, I found
this post by MikeCSG that states the rear measurements are identical with the change being in the rear quarter panel. In a post on the next page, he attributes the track width increase to the wheel width increase. So it looks like my theory was totally wrong.
