New would be great, but I haven't found a replacement that looks like it. I think the '84 was unique, particularly with the shroud for the A/C option.
There are 3 little screws that hold the fan blades on; no center hole for a shaft & nut.
I might find a used one, then I could use the motor bracket as well.
I figured if I could get the armature out without breaking something, I could stick the magnets back on.
