What is claimed is: 1. A method for assembling a gas turbine engine, said method comprising: coupling a combustor within the gas turbine engine, wherein the combustor includes at least two mounting bushings extending from a radially outer surface of the combustor; inserting a pin having a crowned surface at least partially into a respective mounting bushing such that the pin provides both axial and tangential support to the combustor; and securing the pin to a combustor outer casing using a threaded bushing. 2. A method in accordance with claim 1 further comprising securing the pin to the combustor outer casing using a threaded fastener. 3. A method in accordance with claim 2 wherein the pin includes a shoulder, said method further comprising securing the pin to the combustor outer casing such that the threaded fastener secures the shoulder against the threaded bushing. 4. A method in accordance with claim 3 wherein a portion of the pin has a first diameter and the threaded bushing has a second diameter that is greater than the first diameter, said method further comprising inserting the pin through the threaded bushing such that the pin is configured to move in both an axial and tangential direction with respect to a gas turbine engine centerline axis. 5. A method in accordance with claim 1 wherein the pin includes a head portion, said method further comprising: securing the pin to a combustor outer casing such that the head portion is at least partially inserted into the threaded bushing; and securing the pin to the threaded bushing utilizing a threaded plug such that the head portion is movable in both an axial and tangential direction with respect to a gas turbine engine centerline axis inside the threaded bushing. 6. An assembly for coupling a combustor within a gas turbine engine, wherein the combustor includes at least two mounting bushings extending from a radially outer surface of the combustor, said assembly comprises: a pin having a crowned surface inserted at least partially into the mounting bushing such that the pin provides both axial and tangential support to the combustor; a threaded bushing coupled to said pin; and a retaining device to secure said pin to said threaded bushing. 7. An assembly in accordance with claim 6 wherein said pin further comprises a shoulder, said retaining device configured to secure said shoulder against said threaded bushing. 8. An assembly in accordance with claim 7 wherein a portion of said pin has a first diameter and said threaded bushing has a second diameter that is greater than the first diameter, said pin inserted at least partially through said threaded bushing such that said pin is movable in both an axial and tangential direction with respect to a gas turbine engine centerline axis. 9. An assembly in accordance with claim 6 further comprising: a pin having a first diameter and a head portion having a second diameter that is greater than the first diameter, and a bushing coupled to a combustor outer casing, said head portion at least partially inserted into said threaded bushing such that said head portion is movable in both an axial and tangential direction with respect to a gas turbine engine centerline axis inside said threaded bushing. 10. An assembly in accordance with claim 9 further comprising a plug that is threaded into said threaded bushing to facilitate securing said pin to said gas turbine engine. 11. An assembly in accordance with claim 10 wherein said plug comprises at least one opening that is utilized to secure said plug to said bushing. 12. A gas turbine engine comprising: a combustor within said gas turbine engine, wherein said combustor includes at least two mounting bushings extending from a radially outer surface of said combustor; and an assembly for coupling said combustor within said gas turbine engine, said assembly comprising: a pin having a crowned surface inserted at least partially into the mounting bushing such that said pin provides both axial and tangential support to said combustor; a threaded bushing coupled to said pin; and a retaining device to secure said pin to said threaded bushing. 13. A gas turbine engine in accordance with claim 12 wherein said pin further comprises a shoulder, said retaining device configured to secure said shoulder against said threaded bushing. 14. A gas turbine engine in accordance with claim 13 wherein a portion of said pin has a first diameter and said threaded bushing has a second diameter that is greater than the first diameter, said pin inserted at least partially through said threaded bushing such that said pin is movable in both an axial and tangential direction with respect to a gas turbine engine centerline axis. 15. A gas turbine engine in accordance with claim 12 wherein said assembly further comprises: a pin having a first diameter and a head portion having a second diameter that is greater than the first diameter, and a bushing coupled to a combustor outer casing, said head portion at least partially inserted into said threaded bushing such tat said head portion is movable in both an axial and tangential direction with respect to a gas turbine engine centerline axis inside said threaded bushing. 16. A gas turbine engine in accordance with claim 15 further comprising a plug that is threaded into said threaded bushing to facilitate securing said pin to said gas turbine engine, said plug comprises at least one opening that is utilized to secure said plug to said bushing.
