I have an 05 with a Sterring Wheel lock issue - unable to start - can only push it straight.

My shop determined it was a sterring weel lock issue - the parts don't seem to be available from Chrysler - can Mercedes parts be used - what would the part number be?

One person spoke about using a file to cut off the steering wheel lock from the ignition assembly - is this a good fix? - and do you have any pictures of this fix?

Thanks!
