Put this on my show 99 (5.4L w/ 4r100) when I upgraded the transmission pan to an enlarged Derale sump. Glad I bought these instead of relying on Derale to supply a quality seal. Don't get me wrong, they shipped one with a pallet, but it was a cheap flimsy rubber grommet. This gasket is THICK, with metal inserts around the bolt holes. Definitely the quality I'm used to from Moroso.
