Somebody please help me, before I loose my mind!
I have a 77.5 924 and the plastic "clip/clevis" that connects to the ends of my clutch cable has broken on one end. That part is not in production anymore. I don't know what to do! I have tried looking up replacements, but have found none. Does anybody know any replacement piece being made? Or does the later model clutch cables that are one piece fit the old model 924s as direct replacements? Has anyone else had to deal with this problem? It's so frustrating! Any help would be much appreciated! Thanks in advance.

How to build your own clutch cable eyes
I have an extra (used) plastic one I am willing to part with.
I replaced my plastic ones with some metal ones. I purchased them from a fellow board member, but he apparently got them from here. From this thread...
I am curious myself about how a newer cable would work, but have yet to discover the answer.

Goodness, why does it have to be so complicated? Gah!
1- I don't have the tools to build my own, unfortunately.
2- What would you part with the extra one you have for?
3- How do the metal ones work that you replaced your plastic ones with? I see the part you referenced, but what about the pin that's supposed to go with it?
4- Man, I'd really like to know if a later model, one piece, would be a direct fit and would work... That would be so much easier, if so.

What's wrong with the clevis pin fitting shown on the old thread, these are available in plenty of sizes( not sure what the clutch cable end thread is but it will be metric) and with either the security clip or split pin held pin.

I used a pop rivit for the pin, but as scm924s says, there are plenty of other options (like a cotter pin, bolt and nut, bent nail, etc.) that should get you back on the road.

You can have mine for $5 + actual shipping costs.

M6 Long clevis with pin. Available from most engineering supplies/cable manufactures. Find someone who deals in Teleflex/Morse or Cablecraft and they should have thousands

One clutch cable end broke in my car long time ago. At that time, the original plastic fork was stille available, so the complete cable with new forks was installed.

But I didn't want this to happen again, so I had some parts lasercut, which could be welded together and form new forks. Instead of just metal rubbing against metal, I made them so that small ballbearings could carry the pin going across the fork.

I didn't finish them up, since I purchased another engine, which is about to be put in the car this summer, where the new style cable was included.

I haven't done any thorough comparision, but I believe that the new cable will fit the old cars.

If it doesn't, then I will have to finde the lasercut parts somwhere and finish up the "ball bearing forks"

Does anyone have a link to a specific part that will fit as a direct replacement? I can't seem to find anything. I must not be looking in the right places...
I don't have the needed tools to manufacture or alter my own, or existing ones to fit, unfortunately. A direct replacement is what i need, but yet, am not able to find.
Also I am worried that a metal replacement will wear down, due to metal on metal friction. Thoughts?
It would be ideal if the post 1980 924 cables would be a direct fit for the pre 1980 cables, but i have found no concrete info on this as of yet.
Augh!

The clevises linked to above are a direct replacement fit, and included in that link are the pins that accompany the joint.

This pin was missing in the ones I purchased from the board member, but if you were ordering from a retailer, you could get the complete set at once.

As seen in a link from the HOWTO above. . .

I have both the new and old cable somewhere in the workshop, will see if I can find and compare.

The only thing i am worried about, about those metal clips, is the fact that it will be metal on metal grinding. Instead of metal on plastic/rubber.
And yeah, if someone has a set of cables they can compare to see if it'll be a direct replacement, cable-wise, that would be amazing! Or if someone had close up pictures comparing the two cables?

Shouldn't be a problem. The clutch arm is steel and the amount of movement is fairly small.

If you're really concerned you can apply some dry-film lubricant every time you check the oil.

I've seen a picture of someone elses, after about 3 years, and the metal around the clutch arm has been eroded from the metal clevis, it looks like. This is why I am wary.

Here is a new and old cable. The bearing is only there to keep the cables straight.

I can't see why the new one should not fit an old car. The length is a bite different, approx 1/2 inch, but there is still a lot of adjustment in the threaded end of the sleeve.

Oh, they do look very similar. Do the ends (the clevis connection parts) look like the same dimensions up close? Like they would fit the same as the old ones? Also, the metal clip/housing on the end, do you think that will obstruct anything?
