Can anyone tell me the differences between the 1967/68 corvette steering wheels vs the optional (N34) wheels on the 67/68 camaros.

There was no difference; the wheels were the same. However, the 1967 wheel was not the same as the 1968. I don't know what that difference was, though.

Read THIS Matthew. And like Joe indicated, we have no idea what the difference was between the 1967 wheel (P/N 9746195) and the 1968 wheel (P/N 9748390). I've physically looked at both and there really AREN'T any differences that I can see!

Re: 1967/68 corvette steering wheel vs N34 67/68 camaro wheel

I too have always wondered what the difference was between the 1967 wheel (GM # 9746195) and the 1968 wheel (GM # 9748390) as they appear to be the same.

According to Chevrolet Parts History (for service parts) GM # 9746195 was replaced with GM # 9748390 in June 1971.

The 1967 Camaro steering wheel (N34) is GM # 9746195 as per the 1967 Camaro AIM (UPC N34, sheet A1).
My 1968 Camaro AIM does not list a N34 steering wheel but that page might just be missing.

My 1968 Corvair-Chevy II- Chevelle-Camaro Parts Catalog (July 1968) lists the following in Gr. 6.513:

67 ALL w/woodgrain wheel............plastic (walnut)..........9746195
68 ALL w/woodgrain wheel............plastic (walnut)..........9748390

My 1968 Chevelle AIM lists GM # 9748390 as the N34 steering wheel. In the revision box: "7-17-67 WAS 9746195 WHEEL".

The tables for 1967 and 1968 Camaro show that the hub was GM #3930062. However, that's not the original part number for 1967 and may not have been the original part number for some or all of 1968. The original part number was GM #3901310. The 3930062 superceded the 3901310 in May, 1969. I have no idea what the differences were.

Yes, you're right Joe. I don't know how that one slipped by me. I'll change it.

The difference in the P&A 34 (Sept, 68) shows that the 3901310 was "HUB ASSY, plastic" and the 3930062 didn't make that distinction. It just says "HUB ASSY". I know the 3930062 is metal, but I've never seen a 3901310 so I can't verify if it really is plastic or not. My 05D (4th week of May, 1968) Camaro came with the metal hub, so the change was probably made sometime in mid production, 1968. Unfortunately, the 1968 Camaro AIM doesn't show the N34 wheel, so there's no way to know what it says. However, if anyone has a 1968 Nova or 1968 Corvair AIM that shows the N34, I'd be interesting in seeing what it has listed for the hub.

Thanks!

Re: 1967/68 corvette steering wheel vs N34 67/68 camaro wheel

According to the assembly manuals in my library the 6 screws that attach the steering wheel are as follows:

GM # 769611 (early 1963 Corvette), replaced with 9418712 (AIM date change is Jan. 2, 1963)
GM # 9418712 (late 1963 to 1966 Corvette, 1964-1966 Chevelle w/N34, 1967 Camaro w/N34)
My 1967 Corvette AIM does not have a page showing the steering wheel. I assume the 9418712 screws were used on the 1967 Corvette.
GM # 9428089 (1968-1970 Corvette, 1969 Camaro w/N34) - According to the revision box in my 1968 Corvette AIM GM # 9418712 was replaced with GM # 9428089 on June 29, 1967 (near the end of the 1967 production).

I believe that the sizes of the 6 countersunk phillips head steering wheel screws are as follows:

GM # 769611...........10-24 X 1/2" (these were on my "early" 1963 Corvette made in Oct. 1962 believed to be original)
GM # 9418712..........10-24 X 5/8" (my 1966 Corvette did not have the original steering wheel when I bought it in 1979)
GM # 9428089..........10-24 X 3/4"

Can anyone either verify the screw dimensions or make corrections?
What is the correct length of steering wheel screws on 1967 Corvettes?

Re: 1967/68 corvette steering wheel vs N34 67/68 camaro wheel

Dave, I don't have a GM fastener book, but AMK shows the 9418712 to be 10-24 x 1/2" as well. As for the correct length for the 67 Corvette, I would say it was probably the same as the 67-68 Camaro N34 (since the wheels were the same), which was the 9418712, again shown to be 10-24 x 1/2" at AMK. I've never measured mine, but if no one else steps forward with a definitive answer, I can pull my horn cap and take a look for you.

Re: 1967/68 corvette steering wheel vs N34 67/68 camaro wheel

The following relates to a thread that was around about three years ago. It appears to be about one or two years earlier than this Camaro steering wheel thread but would certainly cause the steering wheel hub to be revised. Here is a link to the thread:

https://www.forums.ncrs.org/showthread.php?95245-1965-N36-Steering-Wheel-Step-or-No-Step&highlight=steering+wheel

The thread talked about the 1965 steering wheel hub without a "step" and that the 1967 hub had a "step". The need for a cutout or "step" in the hub was caused by the steering wheel spokes being assembled and tack welded as two pieces (likely a cost savings compared to a one piece stamping). The new design required an overlap at the 6 o'clock hub position on the later models and a cutout or "step" in the hub.

One other trivia fact. The hub is described as a Hub Assembly because there was a splined metal insert that was molded into the hub in order to mate to the steering column steering shaft. You probably would never notice that the hub was molded as two pieces.

One other thought. Steering wheels and steering columns were tested using a "Black Tuffy" dummy that slammed into a steering column/steering wheel combination. The dummy was instrumented to measure forces on its chest. Those forces could not exceed certain limitations. If a steering column/steering wheel combination failed the test, the steering wheel and/or steering column had to be revised so as to meet specs. This could include changing the steering wheel spokes or the wire gauge inside the steering wheel rim, etc. Also the collapse forces designed into the steering column could be adjusted or the aluminum capsule angles changed etc (1967 and later).
