Well, the party's over. Busted the H putting first cap in it last night. ......I'm about ready to throw in the towel on this thing and pay for someone else to do it for me.
Still have few homebrew options....pull H off 81 shaft and use it (would need another u-joint as I lost needles when the H busted and cap shot out of it...factory needles are bigger so can't borrow from old joints). Other option is buy the CV ball for the 81 and replace it, trying to reuse old u-joints. Second option may not be too bad. I would only have to pull u-joint out of H on one side to access CV, but would have to switch back to old tranfer case flange and drill out yoke holes to larger size.
