Shroud retention wafer

An insulative shroud retention wafer comprising:

• (a) a planar base member having a first and a second side;
• (b) first, second, third and fourth cylindrical members extending from the first side of the planar base member and each having an axial pin receiving aperture and an axial center line extending through said pin receiving aperture wherein said cylindrical members are positioned in an arrangement such that a first longitudinal center line extends through the axial center line of the first and second cylindrical members and a second longitudinal center line extends in parallel spaced retention to the first longitudinal center line through the axial center lines of the third and fourth cylindrical members and a first transverse center line extends through the centerlines of the first and third cylindrical members and a second traverse center line extends through the center line of the second and fourth cylindrical members;
• and
• (c) a protuberance peripherally located on the first cylindrical member at a position angularly displaced from the first longitudinal center line.
