Need door lock cylinder and push button shaft

[hearn]

My driver's side shaft is worn to the point that my door doesn't release from the outside as it should.  I would like to buy a couple of these new old stock or remanufactured.  They are listed in the parts manual as Door Lock Cylinder and Push Button Shaft -31.2423 with the specific number for my 1954 model 62 CdV being 700 3040.  I would appreciate any assistance in obtaining this part or as a last resort, a good measurement for the original part so I can build mine up with a minimum of trial and error.  Thanks for any help on this.  Jim

Amazing that no one else has had this problem and solved it.  I hope someone out there has.
