yes,do you want to change the static camber of the wheel,or the castor?if you want to change the camber,this can be achieved with adjustable castor arms,the more castor,the more the wheel will 'fall over' when it's turned.this will mean less wear on the tyre inner edge,increasing the life of the tyre.my sunny has 1.5 degrees static negative,with 6 degrees castor.when you turn the wheel,it automatically starts picking up more negative camber,which sits the tyre flatter to the road,when you take body roll into account.
if you still want to do it with a camber pin,most
suspension places will be able to supply a kit.
or you could get the crossmember redrilled.
