Ignition Shielding Front Clip

[James R.]

I have a 65 with a 365hp engine and a build date of April 1965. The front clip on my ignition shielding is missing and I would like to replace it. I found two pictures of the clip but both of them are different. I purchased a front clip (from LIC) and it is different from the ones in the pictures. Could anyone share a picture of the correct front clip and where I could purchase one if the one I have is not the correct clip?

Thanks,
Jim

My car was built 4-10-65. This is the clip on the original shielding.

Thanks for the picture. Mine was built on 4-9-65. The clip I have is different than what is shown in the picture. Any suggestions on where I can purchase the correct clip?

Jim,

Check the LIC catalog to see if you can find the correct one - the one you got might have been mislabeled or packaged incorrectly. I just did this project on my '66 and the first clip I got from LIC was incorrect as well. But, I did some looking and found the one I got was just packaged incorrectly. I called them and described the clip I received and the package and they sent me the correct one no questions - very easy.

Rob,

Thanks for the tip. Looking at their web site, it appears what they have listed as the "63-64 Late" clip is the one I need. I wonder if the clip they show and package as the 65 clip is actually the clip for the 63-4 late clip?

Re: Ignition Shielding Front Clip

A little more on these clips, from an article entitled "1963-67 Corvette 327 Engine Radio Ignition Shielding Wire Shields & Routing Supports By John Amgwert




The first is what I'll refer to as a "C" shaped clip part number 3824569



The second design clip called the "T" shaped with additional barbs at the top

allowing for better overall grounding contact to the air cleaner on a carburetor Corvette.

Part number 3839334 came into use sometime after March of 1963 (Jim's picture)



The third design contact clip shaped like a question mark ("?").

Part Number 3864672 was specified for the start of 1965 Corvette production. It was initiated by ECR #62499, dated 2-19-64



The fourth clip was "J" shaped with alligator teeth used at start of production 1966

Part Number 3882701.



The fifth clip as specified in the 1967 Corvette Factory Assembly Manual is

Part Number 3904869



The blueprint for this clip indicates that its visual appearance 15 identical with the

previous 3882701 clip; the only difference being that the

part was "neutralized to eliminate hydrogen embrittlement





I have also seen another version of the "J" shaped clip,

one using four punched barbs at the lower top surface

rather than the previous alligator teeth. This clip appears

today on a 1967 Corvette in the 13,000 serial number

range, but I've not been able to inspect other cars to verify

its actual 1967 production usage.

Thanks for the information. Is the article you refer to availabe on the forum or some where else?
The clip I have may be Part number 3839334. Would you have a picture of this clip or is a picture of it
In the article? Again thanks.

Re: Ignition Shielding Front Clip

The article is from "The Corvette Restorer" CD, 63-64 Edition. Would think all the C2 CD's would have the article however.
It is from the Spring 86. Unable to get a drawing of the different styles however they are all in the article.

Re: Ignition Shielding Front Clip

I disagree with that article regarding 65 clips (3864672). According to that article, my 65 has a 63-64 clip (3839334). There is a picture in Noland Adam's book that shows a 65 with the same clip as mine.

Re: Ignition Shielding Front Clip

Found a little more info however unable to post pictures any longer since update to site!
Send email and I'll send you a print of 3839334 & copy of the 65 cover.

Re: Ignition Shielding Front Clip

Here's the sketch from John Amgwert's Spring '86 Restorer article.

Hmmm, let's see; now I have to "Go Advanced" ... then manage attachments (like before), then "add files" button, then "browse" (in my case, to desktop) .... then ???? I give up.

(10 minutes later) Alan -- was able to attach it but can't figure out how I did it [I went through so many false leads]. Will somebody please put a bullet through the head of this "upgrade" .

Re: Ignition Shielding Front Clip

At least you were able to get it somehow! Have not been able to load anything, bet the size has been reduced.
I feel we need better pictures so one can zoom in to those details, but that's just me.
Those look great, did send email to Jim offering to send pictures.

Re: Ignition Shielding Front Clip

In the 65 section in Noland's book on pages 270, 276 or 302, it clearly shows pictures of original 65 clips that are the same as the original clip on my 65. John Amgwert's article is wrong.

[Wayne M.]

Re: Ignition Shielding Front Clip

Jim -- there's contradiction in those pages. Yes, Noland shows the new '65 top shield on pg 302 with the notch for points adjust, but the ground clip is the earlier '63L-64 style (GM engineering dwg of #3839334 on pg. 167). He goes on to say, along with this new distr. shield #3864671, they included a new grounding clip, #3864672 (one digit more than the new distr. shield. GM design dwg on pg.303.

IMO, the only way we're going to settle this is to look at unrestored original cars. The '65 TIM&JG "allows 2 possible designs; early cars like the '64 clip, but most have the later design clip shaped like a question mark". No mention of what the VIN changeover point might be for the 2nd design.

That's why I posted the picture of mine. That's exactly what it is. A 1 owner, 50K mile car that was unrestored. It also has it's ORIGINAL "238" vacuum advance unit.
