Lower Control Arm - GM Redesign Status? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I understand that the lower control arm was redesigned by GM to address stress bending/cracking issues at the bracket holding the endlink. Does anyone know if the GM Part # 22743327 is the original bracket or redesigned version? It's call-out #16 in the diagram included. Obvious I'd want to order the redesigned version to avoid having future issues.

The pic shows the damage to my driver side lower control arm at 23,000 miles. The endlink was still attached to the bracket, I heard a loud "thump" from the rear of the Camaro when making sharp left turns in the prior month to seeing this, though you can see the stress cracks after it was unbolted. I'm using the Pfadt Rear Lower Control Arm Reinforcement Bracket to bolster the OE control arm bracket until I can get the redesigned part -http://www.pfadtracing.com/catalog/product_info.php/cPath/51_52/products_id/242

Many thanks to Matt at East Coast Supercharging for his help on this issue.
