aluminum knuckle, lower control arm replacement?

[Mike Joy]

I'm trying to find a replacement lower control arm with the ball joint installed for my 2014 Silverado 1500 4x4 crew cab short box w/o off road package. Stock with aluminum uppers and lowers WITH aluminum knuckle.

 

Moog says their replacement will not work with aluminum knuckle. I can not find any complete arms that will work with the aluminum knuckle. I ordered Mevotech from rockauto ME CTXMS50153 and 152 - seems the stem on the ball joint is too short everything else seems to fit fine.

 

Any help would be greatly appreciated!!!
