Dieter, I looked in the '55-'58 parts book and did not find that number listed. Some of the numbers are only used at the factory and are not parts book numbers. A friend that works at the local Chrysler dealer told me about that. Larry Everybody I picked up a couple of NOS bumpers at an auction a few weeks ago, they are wrapped in burlap with all the Chryco logos printed on the burlap and the part number is 1553852. My guess is they look like 55/56 Plymouth or Dodge, could anybody confirm the part number, I don't have a parts book for those years. Thanks in advance Dieter |
