383 oilpan numbers

Hi Guys, can anyone give me the correct number stamped on the oil pan that i need for my 1967 383 barracuda swap. the interchange manual states that a 1967-68 pn# is 2863892 for the 383, but i need the number stamped on the pan for easy i.d. The one on my transplant is stamped 187 and it rubs on the center link, all i'm after is one that will work, or a center link that will. thanks for your help Gerry
