[FC] NEED COIL NUMBER INFO can you help?

[Paul Steinberg]

Kent..... and others..  All the coils that I have seen only have a 3 digit number stamped in them.  The boxes that contained the coils would have the 7 digit GM part number.  The only real difference that I have ever seen in these NOS in the box coils was that the boxes varied in size and material.  I know that the Spyder used a higher voltage coil than the standard Corvairs for 1962 - 64.  Can't speak to the 65 - 66 since I never paid too much attention to the details of second generation Corvairs.  I don't ever remember seeing a date code on any GM coils.  As for the part number in the assembly manual, you really can't go by that number sometimes, because that number was only used internally for complete assemblies that were arriving from other assembly plants.  Case in point, is the early model rear axle and bearing assembly.  In all my years of hunting parts, I only came across one NOS axle with bearing installed on it in a dealership and the part number was one digit off from the actual axle.  My guess is that it was a assembly line part that was shipped when someone in the Dealership parts department made a order mistake and lessened the part number by one.  I do know that in the 1960's GM would ship part assemblies to dealerships if they ordered a part that such a number existed for it.  It wasn't listed in the parts book, but part number mistakes happened and GM shipped wrong parts.  That is one of the reasons that so many NOS parts are available today.... MISTAKES in the parts rooms that no one took the time to return.... Paul in CT.....

  Hi,

  As part of my research into what's different about 1965-66 Canadian-produced
  Corvairs (see http://www.corvairkid.com/oshawa.htm), we have been looking at
  ignition coils. You may know that the case of a stock Canadian coil is
  natural-finish aluminum, which looks strikingly-different from U.S. stock
  coils, which are black.

  I also thought that the part number stamped on the outside was different.
  Subsequent investigation by Dave Newell over the past week seems to indicate
  this is not true, however.

  What appears to be the case is that the part installed at the factory (U.S.
  or Canada) used one number for the coil AND bracket. Service replacement
  coils used a different part numbers because the bracket was NOT included.
  The assembly manuals and parts books clearly show different part numbers for
  each application. Comparing the coils we have found so far (U.S. and Canada)
  to the assembly manuals and parts books (U.S. and Canada) seem to bear this
  out.

  Here's where you can help: We need more part numbers from Corvair coils,
  whether they be U.S. or Canadian. Please send me any part numbers found on
  stock coils, whether they be used or NOS. The number should start with 1115.
  The last three digits will be what varies. Also, if there is a date code,
  please include that too. The date code will be one number, a letter, and
  then one or two more numbers. (The first number is the year, the letter is
  the month [I is not used due to looking like 1], and the one or two numbers
  that follow are the day of the month.)

  By the way, our research is showing a lot of overlap among coils across the
  various Chevy lines. I guess this is not too surprising.

  Thanks,

  --Kent
