Very good score brother! She's purddy! Do a lot of thinkin before you lift her, make sure you're at the the height you're going to want instead of having to do it twice!$!
Do a lot of research man, that's my best advice. And when you think you've got the plan nailed, search s'more and then ask more questions. Oh, and learn how to weld! Lord knows I still need to learn...
There's a HUGE difference between wanting A good-looking XJ, An off roadable daily driver XJ, and one of those- Take You Just About Anywhere, Trail-Certified XJ's! Figure out what you're really going to want 1st.
By hooking up with other owners that'll take you/let you drive their rigs, you'll learn tons of 1st hand knowledge. Take it as it is on rides with your new friends and see what she can already do for you, you're going to be surprised at what this thing is capable of already!
Good Luck! And have a good time, that's what it's all about isn't it?!
