What makes the ignition switch on a '65 different than on a '67 Monza?

According to the 1965 Shop Manual, the 1967 Supplement and Bob Helt's "The Classic Corvair" there is NO difference!

In 1968 they added a "key in the lock" switch.

Hope this helps! drinking smiley

The 65 ignition switch assemblycould have the securing outer ring removed, whether or not there was a key in the lock, and it could be removed in any position. In 1966 they changed the design of the inner tumbler and added an "interference" design for the outer ring. This makes it mandatory that you rotate the key past accessory, with the paper clip inserted into the small hole in the face, and remove the tumbler assembly. Then you can unscrew the outer ring and push the switch assembly in and it falls in, down under the dash. Although the complete 68 switch assembly may be installed into a 65, perhaps some terminals on the back side will mate with a 65 harness, or not be used at all. So, perhaps it will work in a 65. The odd thing about a 65, is that it is really easy to steal. Just bring along a 65 switch and key with you. Unscrew the outer ring and push the switch inward. It falls down just under the dash. Replace the installed ignition switch with your own, and off you go!

In '67 they added a terminal that provides a ground in the start position. This grounded terminal is used to light the "Brake" light that was added to the fuel gauge in '67 for the E brake or a brake system failure. This way when you are cranking the engine you can see that the light still works. I was thinking that in '65 you still have to remove the tumblers before you can take the switch out of the dash?

The 1965 Ignition Switch AND Key Cylinder are physically different than the 1966 through 1969 versions. Look at the photo's found in the above referenced link.

The 1965 Key Cylinder has a small "Pin" that when looked at from straight on resembled the Upper case letter "D" while the 1966 and later resembles a lower case letter "l".
The ignition switch will have a matching recess in the plastic part inside that matches the specific year.

The 1936 through 1966 GM Ignition Cylinders utilize the "15" Groove keyway which is known to many as the B10 (an Aftermarket Keyblank Identification number)
In 1967 GM changed the Key Groove and began an alphabetical system of identification. The 1967 was an "A", 1968 was a "C" and 1969 was an "E".
In 1967 GM kept the Octagon Head for some models while using a rectangle shape on other models.
At some point after that, the Octagon shape ignition key was dropped and is one reason that finding that shape head with the correct groove is more difficult today.

It is possible to remove a complete 1965 Ignition Switch with it's key cylinder and replace it with a complete 1966 Ignition Switch and it's key cylinder and have it function correctly.
(This includes using the chrome nut for the specific year as they are different if memory serves)
Since I never owned a 1967 or later Corvair, I can't say with any certainty that they are or are not interchangeable with the 1966 components.

I was only referring to the ELECTRICAL CONNECTIONS! Wasn't looking at mounting. sad smiley

BTW, there is NO Connection to the "Brake Light" from the Ignition Switch in 1967! There is a Brake Light Switch on the Emergency Brake Lever that turns ON the Brake Light when the Emergency Brake is SET (I just came in from the garage where I checked this on MY 1967 Monza!). eye popping smiley

I note that Clark's Corvair lists the 1965 ignition switch with it's own part number that is different than the other years.

When we bought a replacement switch for dad's '65 Corsa many years ago, the electrical plug would no longer lock in place. It "almost" fit, but not quite.

Just assumed it was a fluke and slightly crappy built part (seen it too many times) or a running change (seen that way too many times too) and just made it work with the help of a zip-tie to hold it in place.

Don't remember the details of what clip didn't fit into what hole or why, but I remember the basic issue.
One of these days I'll need to revisit it because I don't like leaving it that way.

My motto... "It's temporary, unless it works!" holes more true than I like to admit!

The "Brake" lamp on the dash is also supposed to light when the differential pressure switch on the distribution block notes a different pressure from front to rear brake circuit. This important function is why the "Brake" lamp should also light during Start.

BTW, I know of no 1967 applications that used the large rectangular head "A" blank. These are known as B-48 in the aftermarket, and became available on 1971 vehicles.

The octagon head "A" blank in 1967 is known as the B-40 in the aftermarket, and octagon "B" is B-42. Both long since discontinued.

Reason for change of head? Steering column ignition switches beginning in 1969. 1968 GM still had dash mounted ignition switch.

I tried to order the 1965 ignition switch (C2428) from Clark's yesterday; received an email from them informing me that it was out of stock and they didn't know when it would become available again.

There is currently one on flea bay.
Clarks price is $99.00 plus shipping and out of stock until who knows when.
The Flea Bay one is $115.00 plus $7.50 shipping and is advertised as NOS
For the difference in price, it is a no brainer in my book.
The OE part number crosses over to the Clarks number too.
I was unable to actually see down into the switch with the provided photo's and confirm it looks correct but....if the switch shown came out of that can, chances are good that it will be correct for the application.

I did see this one one evilbay; didn't know how to cross check the part number as you did.

Thanks for doing so!

I made a counter-offer at slighly below the Clark's price; seller accepted.

Hoping it will fit!

Thanks again.

wow! A hundred bucks for a sixties igntion switch! Guess I've been out of touch for awhile (well, I knew that already) but when did they go from 25 bucks to 99?
I remember when they went from $10 at the local Kragen to $20 or so, but must have pulled a Rip Van Winkle in the meantime.
Or maybe I'm thinking of other cars...

Nice score on the NOS original either way though. Hope it works out perfectly for you.

I needed to get a ignition switch fro my 66 coupe, as I took it for my 66 More Door. Found a NOS one ON EBay for $45. I thought that was reasonable.

If I had a 65, i think I would have bought a 66 switch being frugal and all. Plus switch can't be removed without key. Theft deterrent.
