Topic: '65 Coil Date Code

[Skyway65]

I'm going to get a stamp made to reproduce the information on my original coil.  The problem is the date code is chipped off.  Do the coil date codes follow the same pattern as the other date codes found on other parts of the car?  In other words, would say a "4L18" be correct for a January '65 build date?  Thanks in advance.

Coils are usually a slightly different format.  They would be something like 4LAB, 5AAA.  Year/Month/Week/Shift

Thanks for that Charles-that's what I needed.

My Original  May 66 coil was stamped “6EBC”  which I believe is  6=1966 E=May B=2nd Week C= 3rd shift

The re pop decal I've seen has a code of 7113.  Which would be an early '67 date (?) but with the older style FOMOCO script.  I thought I could use that for the artwork, with a proper date added, to get the stamp made...

I would not suggest just using the repo decal for the artwork - plenty of others have tried that with the coil and other stamps. Just not close IMHO to the original since it appears (like usual) whom every did the artwork just used stock (close) fonts and spacing but when compared to the original its easy to see the differences.

Just trying to save you from going down the wrong road

Thanks for catching that.

Gary,
If you want to split hairs and get it EXACTLY right, I'm willing to help out in the hope that you may have a skill that I need sometime.
I am a CAD Draftsman, and I operated a graphics/sign shop for years.
I will do you an AutoCAD drawing that the stamp guys can work from, that's exact.
Here's what I need:
1) O.A. Ht x Ln of YOUR coil stamping, say to the nearest 0.010"
2) 10 closeup shots of YOUR coil stamping, perpendicular to the coil, each 1/10 of the way around the arc that the stamping falls in
3) The date code that YOU would like to have
It will probably take me about 2 hrs to import the 10 pictures into AutoCAD and draw each letter with the same font and spacing.  Then I'll send you a disk with the AutoCAD drawing and a DXF file for the stamp company.

As I said, maybe you can help me out with somethin' I need in the future.

I made a Autolite stamp for my coil from my original, but I also have a Fomoco. My coil date was dated the same week my car was scheduled to be built. I have attached a pic of the fomoco stamp that I had made just needs the date input. It's in a micrsoft word file if you want me to send it to you. When I made mine in Microsoft word I printed it out on some old clear overhead projector sheets that way I could hold it over the coil to check the match so I could get it exactly right. After I got the stamp made the hard part was stamping the round coil took a few trys.

Thanks for all of the support and suggestions.  Where else but a forum like this would anybody care about such a SMALL detail!  I tried to send PM's to both Twilight65 and Bryan BUT for some reason that feature doesn't seem to be working...OR, I can't figure the right way to do it.   So, can you guys try to contact me and see if that works!! 

[bryancobb]

I'm gonna split my email address into 2 parts to avoid spam.  Just put the 2 parts (not vertical lines) together.

no one has yet mentioned this but i was taught long ago that the stamp should have a curve to it to make it easier to roll it on..........thoughts ??

[Bob Gaines]

You can also fix the stamp stationary and then roll the coil across it . You can have the stamp made up on a rocker base also.  I have not tried that myself but heard from others that are happy with that arrangement. Bob

Dave, I would be interested in seeing the Autolite version you did. Thanks .Bob

[Twilight65]

Here's my Autolite. When I stamped my coil I stood it upright on a table and Also had the stamp on the table and rolled it around it. My original stamp was 3/8" from the bottom of the coil so it worked out pretty good. If you notice on originals there never perfect anyway. Here's a before and after with the restamp.

PS Gary I sent you a PM
