One is deep, one is not.
Could anyone tell me which one I can use.
By the looks of it, one is not milled properly.

There are 2 different styles of control arms, you probably have one of each.

OK thanks.
I guess I'll google styles ...far as I knew it was left and right, then they changed in 2005 to be not compatible on 2003-2004

That's what I meant you probably have a new one and older one?

Cartel

I'm not sure what they changed from 2005
one has SK522304 I43 1019
the other SK522303 H49 1011 this one is shiny and bigger text

The spindle was changed along with the ball joint, the easiest way to see which one you need would be to measure/compare the end I guess and then try to find the matching part number.

Cartel

these parts are for 2003-2004, part numbers match.
I keep hearing about shoddy milling on the balljoint area.

So the shallow one is probably good, the deeper one looks to be iffy.
Not as deep as the Moog ones looked.

Guess not too many people changing control arms?
Anyone?

TBH not really, why change the arm when you can swap bushings? I would assume also most here would swap for OEM if they did as well.
