The dorman #610025 was the correct rear stud for my 50
Thanks Leon

Just got done changing it.
That sucker did not want to pound out.
Put some heat to it and it still would not budge

Finally drilled out the center some, and then put heat on it again and it finally popped out with a few smacks.

I did not have to pull the axel

Thank you all for the help.
