Does the 2011-2012 Clutch Pedal Assembly have the clutch assist spring that came on the Bosses and the 2013s? While removing the spring on my 13, I broke a switch mounting tab, and need to replace my entire assembly. The 2013 assembly is $140 more than the 2011-2012 assembly. If the only difference is that the cheaper one doesn't come with the stupid return spring, I'd prefer to save the $140 and not buy a spring I didn't want in the first place! Part numbers, just in case anyone has the resources to compare these to let me know if there's any other difference (I would GREATLY appreciate it): BR3Z 2455 K (2011-2012) DR3Z 2455 A (2013-2014) Thanks!
