Hy brickman, 40s aren't my specialty, but in most cases I've come across, remove the horn button, remove the horn contacts, remove the nut holding the steering wheel in position, now there might be threaded puller holes and there might not be I'm not sure, if there are threaded puller holes use those with some long bolts and a steering wheel puller to pull the steering wheel off of the steering shaft, if there aren't any threaded holes a jaw puller or some "J" bolts could be used, I'm sure if I'm all wet on this someone will be along with the correct procedure, hope that helps.
