Tell us more about the beams, please. I'm drooling over this build, since the XJ I sold earlier this year might be dropped off at my house before much longer. Either dead motor or fried rear axle. I have access to a free Chevy 350 and a rebuildable 700R4. I also have a Chrysler 8.25 in my shed. Not as good as an 8.8, but I already have it. I also have 4 and 6 inch XJ springs on hand. I can also see where this sort of project could easily get out of hand expense wise!
