The driveshaft along with the truck is still together and drivable so I know the current position of the yoke. I was hoping there was a single wide spline, as Klhansen has suggested. I am in the process of ordering a new yoke and seal so it will be a while before I get to it.
I can't thank everyone enough for all the help and suggestions. I can only speak for myself, but I am sure that this forum has kept many, many trucks on the road and keeps my enjoyment of my truck as high as it is.
I will update my work as it advances.
