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.
...pic... I did not have to pull the axel
Thank you all for the help.
