The pin in that video is a cotter pin. I can’t tell what it’s in. They’re typically used to keep a nut from turning (look at the nut on the tie rod ends for an example) or something similar. They don’t take the place of a bolt to fasten things together.

Here’s an example:

Let's talk about carburetors: I find that the word "quadrajet" is bandied about online, with lots of descriptions that are well less than exact. In fact, if you go to Wikipedia, and type in "quadrajet carburetor", it will tell you that ONLY Rochester made quadrajet carburetors. This is not true. For US made cars of the era of your car (it gets a lot more complicated if we get into foreign cars and later carbureted cars, so let's stick to our knitting with late '60s and early '70s Corvettes), four barrel carburetors were either "square bore", meaning all four barrels had equal sized venturis, or "quadrajets", where the secondary bores were much larger than the primaries. I have a "Holley Double Pumper" on my '70, which is unquestionably a "quadrajet" carburetor. I can provide pictures if you wish, so if you want to stay quadrajet, you are not limited to Rochesters.

As far as I can determine, Quadrajet is a tradename associated with Rochester, the manufacturer of all those complicated carbs used (mostly) on GM products. I also found a couple references where the name (and design?) were licensed to Carter. I believe the proper terminology for describing other 4 barrel carburetors having small primary bores and larger secondaries is "spread bore". A Quadrajet is a spread bore design, but your Holley is not a "Quadrajet".

Aignment shim. Leave it alone

Then the ends of the cotter pin should be bent so it can’t slip out, right?

Hmmmm. I have heard the term "spread bore" before, so I believe that is a more general term for that carb design. Based on some quick searches, supposedly Carter made carbs FOR Rochester when demand exceeded Rochester's ability to manufacture enough carbs to meet the demand. I found no smoking gun for "Quadrajet" being a tradename of Rochester, but also found nothing to refute it.

Whether or not I have my facts straight on trade names (looks like I probably don't), my point is the same, that Nicole is not married to a Rochester carb if she wants to keep her car carbureted instead of going to EFI, and use original air filter parts.

Yes it should be, think they did a quick alignment and didn't bend ends over.
Details details people...
The pin is used to keep the alignment shims from falling down into the frame. Started 68 or 69 using that design of slotted shims.

Gotta wonder how many other half assed things were done to that car still waiting to be found. Hopefully not many.

[Rodnok1]

Well it was 3/4 done and alot left in limbo by Dub... If the current shop did this makes me wonder however.
I'd be taking wrenches and laying hands on most bolts make sure everything is tight if it was me. Suspension parts top of the list, brakes next...

It will bounce out. It just fits through a hole. It was almost all the way out.

They did the brakes. Unable to finish suspension as parts missing.


Picture posted way down in this thread for the sway bar links that are MIA as well.


Total shit show.


We have parts arriving Friday from Zip. Hoping to make SOME PROGRESS.

[Rodnok1]

Oh i saw the links missing... You unfortunately got it back in various stages of completion. Close to a nightmare.
I've worked on partially completed projects... No way to know what's there or not until put it together, something is always missing.. Always.

Lars will be rebuilding a carb I snagged on eBay yesterday.

He approved it prior to my purchasing it. Having it sent directly to him in CO.

But are the shims in? Was it aligned? If so just bend the ends opposite of the looped end so it can’t fall out.

Yep.


It’s so maddening. Even more so for dumb asses like us. We sokt know shit about cars. We spend hours researching minute details.


Not as simple as just looking at AIM as he modified SO MANY THINGS!

Like steering column. Went to start doing things in there and ended up having to purchase all original 68 column mounts because he had upgraded to 77 but only half was installed.

No fuggin telling where all my original parts went.

The wife told me a guy that has a corvette parts store “vette pros” his name is Gary came and took all the parts.

I’ve reached out to humans his SIL with no response this last month as to if they have some of my parts.

68’s have a ton of one year only parts.

Because suspension parts missing only a measuring tape alignment was done by the shop here that installed the brakes.

No idea if shims in. I’ll have to know what the fuq I’m looking for. (I’m stew-pid”. If that pin retains shims I assume they are NOT IN as it was literally barely hanging when I spotted it. Wasn’t holding anything in place.

Here’s a diagram of where the shims go, and it shows the cotter pin.

Thank you!

I’ll have to get a different angle to take a look.

Did it see any shims fall out so maybe they are still up in there.



Every nut/bolt/fastener will be inspected before car is driven for sure!

Once the trailing arms are tightened up the shims can't move. Since it will be aligned when done I wouldn't worry much about it besides bending the pin ends over.

You're cramming a lifetime of learning into a short period... Most of us learned the same way... Hey something looks like it goes here, why is that loose and... Oh shit I forgot to tighten the lug nuts

Ya know this would be the perfect opportunity to justify a four post lift so your back doesn't hurt working under this nor the Jag... You'd be surprised just bringing a car to a comfortable level can do for a bad back.

Excellent! That's a good price for that carb too.
