Like Ranger X said. . Its not that bad..
It is like Changing RA bushings BUT your also going to remove the Front spring and 2 big bolts and 2 small ones..
Junk yard is your best bet. I'm sure people have spares lying around (I know I do) but shipping them makes it not worth while.. Plus.. If you pull it yourself at a u-pull it you will learn how to do it at home...
Which side broke and where's a pic of it... I've never heard of a stock RA breaing.. Now after market/lift ones I've heard of breaking and they can be welded back and reinforced so it shouldn't break again..
IIRC it was Tbars4 that broke his RA a couple times before he got it reinforce enough.
