The 4L80E has the same output spline as did the turbo hydra-magic 400. Your old bolt on yoke should slip into the output but may not have a drilled and taped output shaft for the retaining bolt. I have hand drilled and taped these before. They don’t have to be perfect to hold a yoke in place.  Your other choice to use the original driveline is swap output shafts from old trany. Not great idea as it’s the last part out in tear down. I assume you just installed a used transmission that is the same model and length?? Good luck.

If you have a machine shop that can make and balance driveshafts have them make you one with the proper ends to match your configuration.
When I built custom 4x4 's I had a shop that would make any driveshaft to suit your needs.

you need the drive line out of the van to fit the trans that you just put in and take your old drive line from the orig set up & go to a drive line shop and have them put it all together. sounds simple to me. whistling
