It is held in like a gas or brake line clip.

Thanks for the info! So, does the clip look something like this style clip from NPD? (pic below)

is there supposed to be another clip that holds the cable to the inner fender, just to the right (towards fender) of the brake booster? I ask because there appears to be a need to hold the cable away from the steering shaft before it routes through the firewall

yes, we mentioned it in posts #2,9 and 10

Not really. It looks like that if you removed one side. It is not reproduced by anyone so either NOS, used or make one (thats what I usually do)

Jeff is from the 68 GT 350.

Yep, thats the 68 NJ style. Bet it has CYY or something like that on head

That clip is a 64-66 application only. The retaining type is called a "butterfly clip". You pinch the exposed tangs (wings) and the bottom two spread.

Maybe this post and pictures will help clarify what others have been trying to describe.

If I am not mistaken the speedometer cable routing is the same for A/T regardless of SB or BB. 4 speeds have a longer cable and different routing. The reason for this is A/T cable is on the left side of the tailshaft and 4 speeds on the right side.

The clip below the proportioning valve is difficult to install, you should be able to clearly see the factory hole for the clip looking through the wheel well. You'll probably need two people if your engine is already installed.

So, the cable exits the transmission and is routed through the clip on the transmission cross member it travels up the frame rail to the bolted clamp, begins its loop to the rear engine apron clip and then through the firewall.

I hope this helps.

Sorry to resurrect this one but I'm at the same point where I'm looking for the speedometer cable clip as shown in the attached picture.

In the picture at the bottom is the rag joint.  Lower left bolt is for the parking brake.  Brake lines go from left to right.  Speedometer cable running mostly vertical.

The clip is about dead center.  This area is below the power brake booster.

This was a rather long post, and would summarize it this way:

1. The clip nor the butterflypush  pin is not limited to 65-66 nor the NJ assembly plant.  I'm sure that this is how my Dec 66 SJ 289 car left the factory.
2. It is not limited to C6 transmission speedometer cables
3. If still does not appear to be available.  I can see why Tim Lea would make it, it not too complex of a shape.  The butterfly push pin is available separately from NPD if I recall.

Since it has been a few years, does someone have a source, or have a used one available to purchase?  Otherwise I'll make a few to share with others.

Naturally the one in the picture is MIA, I guess I need to head back to the shop and look much more closely.  Time for spring cleaning.

I found it, almost tripped over it.  I have detailed dimensions and pictures to upload later

Good to hear. I have mine still clipped onto the body, it went through the media-blasting process when I did that a few years ago.

Does anyone have an opinion of what type of finish this speedo cable clip ought to be? My guess is natural steel like the fuel line/brake line clamps were but the "squeeze clips" from the fuel line/brake lines look to be dull zinc plated so is it safe to say these would likely be the same?

[67gta289]

Mine had a light rust patina over it, so I would guess bare steel also.

While we are at it, I have this other speedometer cable clip shown attached to my cable about 14" from the gear end.  But I don't have a picture of where it attaches.  Can anyone help with that?  The assembly manual drawing is in poor condition and does not really help in this case. Looks like the inner fender clip is 377098-S while this clip may be 379816-S32. Thanks, John

EASY! on a C4 or 3-speed, that goes into a hole in the unibody crossmember, on the drivers side near where the long bolt for the trans crossmember bolts in, hard to explain but look at the unibody crossmember the trans crossmember bolts to, you'll see the hole.

[67gta289]

Like here?

The unobtainium 377098-S does not show up in any Ford documents I have, other than the previously referenced assembly manual, whereas clip 379816-S32 shows up all over the place in MPCs and fastener manuals.

I've got a friend who is going to make a 3D image of 377098-S and look at having it reproduced.  He has a small business and makes a bunch of clips and other doodads for the Mopar world so has been down this road many times, successfully.
