Yea stripped some studs myself, Mate all you do is Get some WD-40 spray the back of the studs and where the inserts are.. Get a Rubber mallet, and smash the studs out from the front, give it a good hit several times.. Should pop out from the back.. Once you take out the stud, Insert the new one in from behind and tighten it by using the bolt and tightening the stud through the hole tell you see its flush and inserted all the way through..
