sounds like you've got one from a granada
they are iirc 12mm longer than the sierra ones
if the camber is out then that would be the first port of call

also, assuming you've got cossie ones in there, there is also the issue of the cossie useing M12 bolts rather than the M10's of the other versions so if you had the other ones fitted you've have to swap the buhes over in the first palce
