[SCG] FW: Need your help: Ignition coil part number survey

[Kent Sullivan]

Hi folks,

If you have any original coils, please let me know.

By the way, I was wrong about U.S. coils a little. They have only the last
three digits of the part number and no date code.

Here's a very helpful table from Bob Helt:

             Assy.             AMA             Parts
Year       Manuals            Specs          Manuals

1960       135                  135              087
1961       135                  135              087
1962       135/172*          135/172*       087/091*
1963       135/172*          135/172*       087/091*
1964       135/172*          135/172*       087/091*
1965       200                  200              202
1966       200                  200              202
1967       200                  200              202
1968       208/412              208              202
1969       412                  412              202

* = Turbo engine

So far we have seen every number in U.S. coils except -091. On the Canadian
side, we have seen -135 and -200 so are hoping to see many more of those.
Canadian coils have a natural-finish aluminum case, the full part number,
and a date code.

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
