rear trailing arms

I'm in the process of upgrading my complete suspension on my SF5 S and have decided on KYB AGX struts w/Tein springs/ F&R Whiteline 22 mm sway bars w/upgraded bushings/ Whiteline F&R endlinks/upgraded adjustable laterial links. I want to add adjustable pillow ball trailing arms and read in an online Subaru forum (forgot which one) that the rear trailing arms for a 2010 Camero is a direct and less expensive fit. Can anyone confirm that the 2010 Camero rear trailing arms will fit? Whiteline has an older model Camero trailing arm which is still available at less than $150.
