TNT Autosport.com is looking to sell the NOS/NX systems. However, I cant seem to find part numbers that would work for the Cobalts.

First person to post up some part numbers (One for NOS, One for NX) will receive some store credit.

 

According to LMPerformance, NX kits are part numbers 004416 and 004417. Someone might want to double check those. Says for Cobalt 2005-2006.
