Yeah dang, I thought I was crazy starting my project with a '92 with 280,000 miles on it. You got me beat!
My build is going to be a tad milder than yours. I'm not lifting, but going with lockers, bumpers, winch and sliders probably. I already did the manual hubs.
I'm going more for the expedition, back country vehicle than a crawler or mudder.
I already did balljoints, and when I got the center link done under the toyota service bulletin, they redid all the steering for me, except the idler, free of charge. How nice of them
Other than that, I'm doing like you, replace and rebuild as needed. I just hope I have no breakdowns in the boonies.
