I used super glue to hold it together, then I ended up using Gorilla Glue (which is what I had on hand) I built up a complete cast around the outside from the holes on the coil ears to an inch down the shaft and was able to spread it on the inside as well. I ground down the inside enough to slide the coil connector through. It seems to be rock hard solid. I installed the new lower shaft I bought but not before building up a cast around the outside like I did on my broken shaft for added strength. I think it will be fine for a spare.
Appreciate all the helpful ideas that I can fall back on if my attempt doesn't hold.
There are epoxies that adhere to plastic quite well- just look for it on the label.
Always, but always, I cross hatch the area to be glued with a razor knife, then coarse sandpaper, and then acetone or non lubricant ether(starting fluid).
I have even used brake cleaner in a pinch.
