If I remove the speedo gear drive unit, I can get the cone to fit down snug if I wiggle the stub axles a bit. But I am unable to insert the speedo drive unit at that point and, with the drive unit in place, cannot get the cone to drop into place.
This shouldn't be such a difficult task!
1) Patience
CHECK2) Use a dab of grease to hold things in place.
I THOUGHT OF THIS BUT DIDN'T KNOW IF IT WOULD HURT ANYTHING IN THE GEARBOX3) The mating surfaces should be flat and mated before anything is tightened
YEP4) Never force anything. Leave the BFH in the tool box.
AGREED5) Work on the trans in vertical orientation. Don't try to fight gravity.
CHECK6) Dr. Evil video
MIGHT BE OVERKILL FOR THIS PARTICULAR SITUATION Thanks, all. I will try again this evening.
