Up for Buy-It-Now is a new old stock left and right hand steering knuckle assembly, Mopar casting numbers 870922 & 870921.  According to limited research on the internet and my vintage Mopar Manuals,  I believe this to be Mopar numbers 807920 and 870919 and used on the following models and years:

1946, 1947 and 1948 Dodge, DeSoto Chrysler 6 cylinder,  All models except 7 passenger, Limousine and Town and Country.

  As always, please refer to your own individual manuals to verify these are the parts your need, as there are only casting numbers on each knuckle and I cannot confirm the applications listed above.
  The steering knuckles are in brand new, never used condition and each show no indications of ever being mounted or installed. They are still covered in an extreme amount of  heavy protective dried grease from the manufacturer.  The left knuckle does has some minor surface rust on the machined shaft from many years of shelf storage.  May or may not need a light polishing up with an emery cloth before installation.  The right hand assembly has the original cardboard protective sleeve on the shaft from the manufacturer.
  Please feel free to E-mail me questions.  International bidders are always welcome.  Thanks for looking!!!!
