The first eccentric bushing is configured to receive the second eccentric bushing in the first eccentric aperture. The second eccentric bushing is configured to receive the fastener in the second eccentric aperture. The first eccentric bushing is rotatable with respect to the second eccentric bushing to adjust a position of the fastener with respect to an adjacent component to which the fastener is being attached. ## Claims ### Claim 1 A fastener aligning joint arrangement, comprising: a first component comprising an oversized aperture; a first eccentric bushing comprising a first eccentric aperture and a first head flange, the first component is configured to receive the first eccentric bushing in the oversized aperture; a second eccentric bushing comprising a second eccentric aperture, a second head flange and a second shaft portion extending from the second head flange, wherein the second eccentric aperture extends through the second head flange and the second shaft portion, and the first eccentric bushing is configured to receive the second eccentric bushing in the first eccentric aperture; a fastener, the second eccentric bushing is configured to receive the fastener in the second eccentric aperture; a washer configured to be received around a portion of the second eccentric bushing; a snap ring configured to be received around the portion of the second eccentric bushing to secure the washer in an installed position and wherein the washer and the snap ring axially lock the second eccentric bushing within the oversized aperture with the first head flange against the first component; and a second component comprising a fastening aperture, wherein the fastener is configured to be threadingly coupled to the fastening aperture. ### Claim 2 (depends on 1) The fastener aligning joint arrangement of claim 1, wherein rotation of at least one of the first eccentric bushing with respect to the first component or the second eccentric bushing with respect to the first eccentric bushing is configured to align the fastener within the oversized aperture. ### Claim 3 (depends on 2) The fastener aligning joint arrangement of claim 2, wherein the first eccentric bushing comprises a first shaft portion extending from the first head flange, wherein the first eccentric aperture extends through the first head flange and the first shaft portion. ### Claim 4 (depends on 3) The fastener aligning joint arrangement of claim 3, wherein rotation of at least one of the first eccentric bushing with respect to the first component or the second eccentric bushing with respect to the first eccentric bushing is configured to align the fastener with the fastening aperture. ### Claim 5 (depends on 4) The fastener aligning joint arrangement of claim 4, wherein the first component comprises a depression and the snap ring and the washer are disposed in the depression. ### Claim 6 (depends on 4) The fastener aligning joint arrangement of claim 4, wherein the fastener is configured to be tightened to compress the first head flange, the second head flange, and the first component between the fastener and the second component. ### Claim 7 (depends on 3) The fastener aligning joint arrangement of claim 3, wherein the first head flange of the first eccentric bushing comprises a pair of parallel opposing surfaces configured to receive a first tool for at least one of securing the first eccentric bushing in a first given rotational position or rotating the first eccentric bushing between a first rotational position and a second rotational position. ### Claim 8 (depends on 7) The fastener aligning joint arrangement of claim 7, wherein the second head flange of the second eccentric bushing comprises a slot configured to receive a second tool for at least one of securing the second eccentric bushing in a second given rotational position or rotating the second eccentric bushing between a third rotational position and a fourth rotational position. ### Claim 9 A double eccentric bushing arrangement, comprising: a first component; a first eccentric bushing comprising a first eccentric aperture and a first head flange; a second eccentric bushing comprising a second eccentric aperture, a second head flange and a second shaft portion extending from the second head flange, wherein the second eccentric aperture extends through the second head flange and the second shaft portion, and the first eccentric bushing is configured to receive the second eccentric bushing in the first eccentric aperture; a threaded fastener, the second eccentric bushing is configured to receive the threaded fastener in the second eccentric aperture; a washer configured to be received around a portion of the second eccentric bushing; and a snap ring configured to be received around the portion of the second eccentric bushing to secure the washer in an installed position and wherein the washer and the snap ring axially lock the second eccentric bushing within the first component with the first head flange against the first component. ### Claim 10 (depends on 9) The double eccentric bushing arrangement of claim 9, wherein rotation of the first eccentric bushing with respect to the second eccentric bushing is configured to align the second eccentric aperture with a fastening aperture of an adjacent component. ### Claim 11 (depends on 10) The double eccentric bushing arrangement of claim 10, wherein the first eccentric bushing comprises a first shaft portion extending from the first head flange, wherein the first eccentric aperture extends through the first head flange and the first shaft portion. ### Claim 12 (depends on 11) The double eccentric bushing arrangement of claim 11, wherein the first head flange of the first eccentric bushing comprises a pair of parallel opposing surfaces configured to receive a first tool for at least one of securing the first eccentric bushing in a first given rotational position or rotating the first eccentric bushing between a first rotational position and a second rotational position. ### Claim 13 (depends on 12) The double eccentric bushing arrangement of claim 12, wherein the second head flange of the second eccentric bushing comprises a slot configured to receive a second tool for at least one of securing the second eccentric bushing in a second given rotational position or rotating the second eccentric bushing between a third rotational position and a fourth rotational position. ### Claim 14 (depends on 13) The double eccentric bushing arrangement of claim 13, wherein the second shaft portion comprises a circumferential groove configured to receive the snap ring. ### Claim 15 A method for installing a component, comprising: disposing a first eccentric bushing comprising a first eccentric aperture and a first head flange into a first aperture disposed in the component; disposing a second eccentric bushing comprising a second eccentric aperture, a second head flange, and a second shaft portion extending from the second head flange, wherein the second eccentric aperture extends through the second head flange and the second shaft portion, into the first eccentric aperture; disposing a washer around the second eccentric bushing; disposing a snap ring around the second eccentric bushing to lock the washer in an installed position and wherein the washer and the snap ring axially lock the second eccentric bushing within the first aperture of the component with the first head flange against the component; rotating the first eccentric bushing with respect to the second eccentric bushing to align the second eccentric aperture with a fastening aperture of a support structure; and disposing a fastener through the second eccentric aperture to couple the fastener to the support structure via the fastening aperture. ### Claim 16 (depends on 15) The method of claim 15, wherein rotating the first eccentric bushing with respect to the second eccentric bushing comprises: moving a first tool around the first head flange of the first eccentric bushing; and moving a second tool into a slot disposed in the second head flange of the second eccentric bushing. ### Claim 17 (depends on 16) The method of claim 16, wherein the first head flange comprises a pair of opposing parallel surfaces configured to engage the first tool.
