the 3/8" would be the best but if you can get that you should still be ok. just taper to the large diameter of the taper. the nut will pull the stud down to seat it. 
from looking at you pictures i don't see anything "messed up." they could have heated and reshaped the spindle arms some but you'll be just fine like they are.
fun solving these lil screw ups huh?

		 I thought about it but wasn't sure the purpose of the taper.  In fact, just yesterday my son-in-law suggested drilling it out and using different rod ends.  We'll see what happens.
