I recently purchased aftermarket floor panels but havent received them yet. They were $99.99 on Ebay. They looked good but were not from the Big 3 I was looking at what was left of the old floors and noticed a "1/2 high X 1&1/2" wide "ridge" on the floor panel that runs the perimeter of where the trans housing meets the floor panel. From the picture of the panels I bought, it dosn't look like the panels I ordered have this ridge? Anyone ordered floor panels from other than the Big 3 and did they have that "ridge" or do they come without and that's why their cheaper?
