Anyway, to anybody posting answers, do your research or don't make suggestions unless you are informed, bringing undue concern to Original Poster, and yet not adding any value at all - to the contrary adding confusion.

The lower front control arm must be one of Mitsus experimental labs where it goes one step fwd and two steps back. Thus double R&D time - which explaines the hi cost on these cntr arms - I guess
Anyways, there are two different designs on the E6, by name the E5 as in my opener and the E6 as described by Todd. Both came to use in E6, the E5 in my RS. Porbabely because it is the lighter version than the "two piece design". Basic Geometry is equal, but you cannot use both types on the same car. The 2 pc design has the ball joint assembled upside down. So you would need to have a different knuckle all the way. Anyways, both types were referred to as CP9A, so fell free to feel confused!
The E7 CT9A is a totally different design besides being one piece again. The cntr arm itself and ball joint as well. You could not use an E7 CT9A onwards ball joint in the one piece cntr arm on an CT9A. Do not mistake one by the other. The E8 CT9A again has received an ECN, larger ball in ball joint here.

So, as far as replacing the entire cntr arm on the front suspension you will need to physically examen what your wheels suspend on, take a picture or the car with you when you place your order. Hopefully that sales/mechanic is in the knows.

After this being clarified I would like to know if someone has performed a ball joint replacement on an MR455758 arm with a MR485675 ball joint that is? And how?

Att. you see my cntr arm, the one piece design CP9A.
I could document each detail mentioned above easily - just haula.
