Here are some Nos 71-2 and 73-4 door handles. They are exact on the outside. It's the difference on the inside mechanism part. The 73-4 have longer plates on them where the lock rod attaches. I believe they both fit in the door openings as they are the same openings 71-4 if I remember. Hope that helps...71-2 is blue box and 73-4 is the tan cardboard one...
