Different LCA's?

Summit and QA1...who packaged both. Im assuming the 2 came in 2 boxes or a "matched set"? I would believe 2 boxes would be easier to foul up but 2 in the same box as a set would be pretty easy to see a difference when they were packing them. Get a pic out to them with a ruler showing the F up. Those guys should know their products! Now. What LCA did you get? What Mopar has a different LCA that matches your bad ones specs. E-body, F, B?
