A mounting pin arrangement adapted for attaching a first structure and a second structure together, the mounting pin arrangement, comprising:

• a circular sleeve positionable within the first and second structure, the sleeve having a first end portion and, a second end portion and a bore extending axially therethrough, the sleeve includes a plurality of adjacent sleeve segments having an elastomeric material between and connected to adjacent segments and an elastomeric end cap on the first end portion, the sleeve segments being of a different material than said elastomeric material;
• a first insert positionable within the bore of the first end portion of the sleeve, the first insert having a bore extending axially therethrough;
• a second insert positionable within the bore of the second end portion of the sleeve, the second insert having a bore extending axially therethrough;
• and
• a fastener positionable within the bores of the first and second inserts to move the inserts axially toward each other within the bore of the sleeve assembly to expand the diameter of the circular sleeve assembly.
