A SYE and driveshaft will cost you about 500.00
WARNING a SOA done right will cost you just as much or more thn a good SUA lift and you can really ruin the driveability of your jeep if you dont know what you are doing, best thing I can tell you is resech it for a couple months gather all thee parts and tools and then get someone to help you.
