Is that the black plastic gasket with the double ( super thin) o ring type perimeter seal? They work [censored] with cast aluminum pans, I have that one on my 727 but it doesnt seal with the deep 904 mopar steel pan.
Whats the part number for the grey ribbed steel reinforced silicone gasket? Do they still make that one?
I just use the cheapo cork gasket.. it dont leak with the cast pan.. I just use the stock cast pan on the 518(727) but its deep
