Claim:
A prosthetic component comprising: A. a second piece comprising a flange lying in a plane and having four walls upstanding from said flange, wherein: i. said second piece has four holes there through at respective intersections of said four walls and through said flange for being connectable to an adjacent prosthetic component; ii. said four walls define an opening; and iii. each of said four walls has a hole there through for receiving a screw; and B. a first piece comprising: i. a body with a first side and a second side; ii. a positioner on said first side of said body; and iii. a dome with a centrally positioned pyramid on said second side of said body, wherein said positioner is receivable within said opening and is smaller in size than said opening to enable said positioner to be selectively and adjustably placed within said opening, wherein said positioner is fully movable within said opening to a selected location whereby the positioner can contact up to two of said four walls simultaneously, and wherein said hole through each of said four walls is angled relative to said flange so that the screws can hold said positioner in the selected location without contacting the body of said first piece.
