Default Question RE Clutch Fork Release Rod

So I got my new baby home and she decided to have a temper tantrum first day of ownership.
The Clutch Fork Release Rod snapped clean in half. I have a question about the way the old vs the new part looks though.

The parts have a 90 degree bend on one end. What's weird is that the new and old parts have their bends exactly opposite of one another.
The old part came through the back of the clutch end with the cotter pin facing drivers side.
The new part went through from the front of the clutch end with the cotter pin facing the passenger side.

Not sure it matters, just wondering if one or the other design is better or wrong?
​​​​​​​This is what the new part looks like:

And the one I took off is definitely opposite.

This seems very curious. This is almost purely a linear force one way or another. Any idea why it broke?

There are better parts available, look here for instance

No ideas why it broke other than... 49 year old metal??
As long as it doesn't happen again I'll go with that.
If it snaps again then something else is obviously wrong. Let's hope that's not the case.

I'll look into better later, the $20 Eckler's part got me going so I could drive it today.

It may not be the reason that the thing broke but the rod is placed in the cross shaft backward. Turn the rod over. The cotter pin ( spring clip ) is toward the engine not away from it. The rod from Ecklers is correct. Maybe who ever had the car before screwed this up.

Well, the spring clips on the old one were towards the engine as you can see in the picture.
I wonder if it was a Chinese replacement part that was designed incorrectly.

Looking at your old rod, it's strange how the front piece looks newer than the rear broken piece. Looks like there are grind marks on the shaft like it's been welded together at some point.
The rod on my '71 LS5 is mounted like the one in Alan71's photo.
Your new rod should last 50 plus years.

You're lucky that you can drive to Ecklers and pick up your parts.

I think the only problem with that bracket is that it is easy to install it without a second thought. I played with how mine is positioned a couple of times and found that if it is turned outward so that it effectively lengthens the clutch fork, it works better and reduces clutch effort significantly.
