Well as far as the budget goes, the wife will probably let me get away with around a grand every month. I told her I would do everything in increments so that I will be able to make the right choices while learning what they are at the same time rather than just buying everything at once and finding out I should have done this instead of that and whatnot. Plus I think the building of it all will most likely be everchanging and neverending anyway.
So your saying that the XJ u joints and axles are compatible with the YJ's? Good advice. Ill look into it.
I like quadratech's website the best too. Its very informative and user friendly. I know how to do the work, its just all the technicalities and size, rating, and compatibility that I need help with. I've always repaired cars. I've never had the luxury of being able to have the freedom of making them better.
