Ignition Coil Primary Wire Connections -- Guide, Support, etc.
« on: December 22, 2023, 09:17:08 PM »
Does anyone know where to obtain the thin, stamped "guide" (or support) that go onto the ignition coil + and - primary terminals?  If I recall, GM used these items on each terminal of the ignition coil for most of their cars from the mid '50's thru the '70's.  These "guides" are the first thing that go onto each coil terminal, followed by the negative wire (from the distributor) and the positive wire (from the harness), and then followed by the #10-32 nut and lockwasher.  These "guides" were made from thin sheet metal (~ 0.020" thick) and had two opposite ends turned up as flanges (about 0.035" high).  These two upturned flanges on the "guide" served to prevent the legs of the wire harness terminals from spreading apart excessively when tightening the #10-32 nut.

I've tried AMK Fasteners and various restoration parts suppliers of replacement coils and they do not have these "guides".  Any help would be appreciated.  Thanks.

Hi Mitch,

Thanks for looking.  I was a bit surprised to see there are three upturned flanges and one long, narrow tab on the part.  I was expecting to see only two upturned flanges on opposite sides.  Perhaps my memory is failing me.  Is the one you found definitely the style Chevy used in the late 60's?

^^ You are correct Normally just two up turned flanges and no locating tang.

I often just buy one dollar Junk swap meet coils to harvest hardware and refinish plating or surface finish
