with the benefit of heinsight, not so easy. i forgot to mention that it was an opel vectra not a vauxhall. there are 2 star bolts at the back of the steering wheel which need to be removed before airbag can be removed. also the steering wheel is a press fit so wd40 and patience are required, plus the thing is spring loaded so when it comes loose watch out. as for removing the egnition, a dot punch and a good hammer and lots of patience. hope some body finds this helpfull.
