I ordered my FR1400 kit after asking a couple of times if it fits with the unmodified Ford Racing cover, I think it was about 2 months ago or so, you were already selling the Ford Racing covers at that time so I doubt it's an "early" kit.
Our early Delrin isolated rear diff lowering mounts that we sold in 2010 and early 2011 would not fit the New ford Racing cover that did not exist at that time.
I think the Ford Racing cover came out about mid 2011.
