I’ve gotten ne down this road with my 72 and if I can remember the lock barrel doesn’t come out it’s attached to the column. I snapped my only key and had to firstly find a blank after going to 5 locksmith ,found an old guy who was into old small fords.
Then got mobile locksmith out to do his best to get a key made to suit lock.
Was successful but t.b.h u can start most old fords with your finger nail.
