hiya mate, i have the same problem with mine. my side bolt is ok so i have taped over one of the rear ones and slightly nip up the other, then tape up the rear to the frame making sure there are no gaps, then put the mud gaurd back on and tape up the rear too making sure no crap can get in. it works for mine mate. my mate took his threads out and super glued them in but they still keep spinning round after a couple of changes...good luck!
