Coil Pack 2003 Vue 3.0 6cyl where to find

My 2003 Vue is running rough and I am told it needs to have the coil pack replaced. I have tried all the auto parts stores and they list the 4 cyl ...but not the 6 cyl..I will try the junkyards but would like a new coil...it appears to be mounted on the top of the engine drivers side and has two wiring harnesses attached to the coil packs..I believe the ecm is below..any ideas...is the location correct?

Well,using stuff from the junkyard wont do any good as it has no guarantee and besides it would end up running rough.A brand new saturn vue part (http://www.satpartswholesale.com/saturn-vue-part/) on your car is better yet a good choice.
