Too bad you're not a little closer to Tennessee! I'd be happy to walk you through a rebuild. The main sticking points are the clearance between the clutch plates, the end play of the front and rear main shafts, and the "touch" required to assemble the clutch pistons in their housings without cutting the rubber seal lips. There are some assembly aids available which makes the clutch assembly a lot simpler, but they're expensive for a one-time use. I made a lot of my own assembly tools, rather than pay the price for Kent-Moore equipment, a major supplier of transmission specialty tools. One thing to avoid at all costs is a "shift kit". All they do is mess up a good transmission, and do major damage to rear axles.
