New-to-me RS6, V#905530 , parts needed list

[LIRS6]

To-Do
Very heavily considering picking up the Wagner IC's being offered here, full kit will run me ~$1500 and hopefully help charge temp when I'm sitting in DC area traffic in the summertime. Pretty certain install requires removing front bumper, and I haven't had enough hands-on time with the RS6 to be comfortable doing something like that in a day / over a weekend yet.

Front bumper removal is pretty straightforward - if I could do it, you can. I replaced pass side IC (with stock) - but from what I recall reading in posts, that's the easy one (vs. driver's side).
