I just bought a 78 C3 and found the throttle cable being held in place with zip ties. What is the best way to fix this? Is there still a part available, which part do I need? Pictures attached.
I tried blowing up that photo. It looks like that bracket does have the square hole in it. You may wish to double check that.
But if the plastic clip no longer wishes to remain clipped into place. The only good fix is to replace the cable. Available from most of the Corvette vendors. Possibly available from Summit but I didn't check.
tie a string to the old one before you pull it through the firewall. Then tie the string to the new one to help pull it through the grommet.

You have a pile of custom, aftermarket parts that don't work and don't fit together. Either put the correct stock parts on the car, or use good quality custom parts and make them work right with good modifications and well-done workmanship. Your throttle cable is a cheap aftermarket braided cable that doesn't belong on the car, and the throttle cable bracket is some aftermarket adapter bracket that is poorly done and badly installed. The stock, correct bracket looks like this. It bolts firmly to the carb attach bolts, and it fits the stock cable correctly:
The stock cable looks like this:
You have an aftermarket intake manifold, and probably have an aftermarket square-bore carb that won't permit use of the good, stock cable bracket. When you modify your car and eliminate the well-working stock components, you have to be prepared to do well-done mods to make things work - you have a pile of badly done mods there that needs to be completely re-done.
Either install the correct, stock parts, or put some work into your custom modifications to make them right. There are good quality (not cheap) aftermarket parts available that work well if you don't want to go stock. They are not the parts you have...
On my car when I switched the intake manifold and carburetor, I cut and rewelded the original bracket so my original throttle cable worked perfectly with my Holley carb.
Then years later I cut it up and welded again so my factory throttle cable works perfectly with my EFI.
And it's tidy, and workman like.

Your profile is not filled out so I'm gonna guess that you have a 1978 from your "handle".
Here is a throttle bracket from Corvette Central for a 1978.
Does that look like it would work? https://www.corvettecentral.com/c3-6...bracket-353128

The bracket isnt the issue, its the incorrect throttle cable. Is your pedal stock? It looks like a braided housing which is an aftermarket Lokar or a knock off. If you dont have a stock pedal then that could be an issue using a stock cable

i don’t know if the pedal is stock. I just got it and trying to figure out what is what. I am also new to owning corvettes and I was a baby when my corvette was made so I am starting from scratch.
We are glad that you have joined us here at the forum. This place has some incredible experience and the members are always trying to be helpful here. If you have any questions regarding a C3 Corvette this is the place to ask them!
One of my favorite things reading and learning about the various problems and how to solve them. There is so much to be learned from these members!
If you are going to do Any Work on your car get a AIM and Chevrolet Service Manual for your year car, they are easily found on eBay. Also several of the vendor cats will show illustrated parts breakdowns. Welcome to the Forum.
I’m with Lars on this. Can we get a couple more pics of the engine without the air cleaner so we can see what all you have going on. I’m partial to Lokar cables and brackets but need to see what all is going on there first.
not true, brake pedals are wider on an automatic tranny car
I took it as a joke about it being too big - Bikespace is unapologetically a 4-speeder through and through.
However... why IS the automatic pedal about 3x as wide as a manual pedal? Is it just to fill the foot-well space? Back in the day we were taught to never use the left foot for braking, so it doesn't make sense that it's widened for that.
Side story: When I was first starting out, I was a photographer's assistant and was driving his car with him in the passenger seat. When we came to the stop sign at the end of an exit ramp, I instinctively, and firmly, pushed the clutch pedal in... to say he was surprised at unexpectedly lurching forward toward the dash was an understatement — the car was an automatic.
