Need a brace - 8BA to BH

[Ross F-1]

My truck has an 8BA/EAB Car engine in it, with an oil pan that has the three studs on the pan. I am lacking the bracket or brace that goes from the three studs to the bellhousing. I only have Truck parts books, so I don't have a way to confirm this p/n, but I believe it is 8CM-6825. I realize that is a Merc part number, but I believe I have the Merc oil pan (below). It has the internal tray.

Does anyone have a spare of this piece they would want to part with? Is that the correct P/N?
