I went to the local Napa store today to get some studs for my future tranny pan skidplate project, filter and gasket for the pan and to try and find a nut and plug to put onto the pan to make draining it simpler in the future. I was delighted to find out that they stocked a bolt on drain plug kit (Napa PN 704-1914) for the aplication. Here's how it looks on mine installed. With the mandatory Ford Blue.
