Everyone knows what they know, and believes what they believe. And noone is going to be changing anyone's mind about what they know.

Can we all just agree on that?

No, Midyear, like the "C" designations, is a later invention, at least on a national scope. (maybe they were called that in some local areas). They were more often called "Stingrays" (speaking verbally, not getting into the 2 words vs all one word).

I have looked through late 60's and early 70's Corvette News, NCCC Competition Rulebook, Vette Vues, and numerous magazines and magazines special editions. For example, "Fabulous Corvette" published in 1971. Nowhere in any of those does the term "Midyear" appear. There's nothing terrible about it, but it's something that came along I'd guess mid to late 70's if not later. Who has the earliest printed use of the term?

Regardless, the term has approached religious status to some, and even has to be capitalized! To those folks "C-2" is blasphemy!

And since we are up to C-7's, I guess my '92 C-4 is now a "midyear"!

C1 is a lot easier to type and makes no different designation than solid axle. Same for C2 and mid-year.

One quick example. If I asked someone to help me locate a rear axle bearing for a C-1, what bearing would be recommended to me????? Well, guess what, from 53-62 there were a total of FIVE rear axle bearings. SOOOOOOOOOOOOOOOO, the YEAR MODEL and rearend type would need to be known!

Again, labeling these cars by a C-category just DOES NOT WORK![/QUOTE]

I know of 3 (56 being a one-year only), what are the other 2 of the 5?

The C1 section would be quite lonely. Its this way for a reason.

1. 53-55
2. 56
3. 57
4. 58-62 (std ball bearing)
5. 58-62 (roller bearing for posi rears)

Something that MANY people do not know, is that the 53-55 rears were virtually 51-54 pass cars. The MAJOR difference between a 53-55 Vette rear and a 51-54 pass car rear is the PINION gear (NOT the ring gear). The 49-54 Chevy pass cars had the enclosed (torque tube) drive shaft. The 53-55 Corvettes had an open drive shaft style rearend. Thus, 53-55 Corvette pinion gears are machined (splined) for a pinion yoke and U-joint. Pass car pinion gears were directly connected to the enclosed drive shaft INSIDE a torque tube. Otherwise, ALLLLLLLLLLLLLLLLLLLLL the guts of a 53-55 Vette rear and 51-54 pass car (49-50 were ever so slightly different) rearend guts, axles, brake backing plates, rear brake parts, and all attaching hardware, are the same. The MOST DIFFICULT part to locate (if not impossible) for a 53-55 Corvette rear is the pinion seal---------------------it is unique to ONLY 53-55 Corvette rears------------no other car.
Also, 53-55 Corvette (and 49-54 pass car) axles are a C-clip style. Thus, the axle shaft of 53-55 Vettes and 49-54 pass cars use a bearing WITHOUT AN INNER RACE, and a separate outer seal. Both were pressed into the end of the axle tube.. The axle shaft itself is the inner race (you know, like 64-later Chevelles, Camaros, Novas, etc).

The 56 Vette and 55-56 pass cars used the same axle bearing (RW507 series).
The 57 Vette and 57 pass cars used an RW307 series bearing (ONE YEAR ONLY).
The 58-62 Vettes and 58-64 pass cars used the RW607 bearing, which was a ball bearing and Vettes with FACTORY INSTALLED posi got a roller bearing.

Oh ya, all the above axle bearings, EXCEPT the roller bearing) and seal for 53-55, are still available. BUUUUUUUUUUUT, the 57 only (RW307 series) bearing seems to be getting a little more difficult to locate. (I have several on the shelf)

At one time I had a 60 Corvette project I was doing. Then I found this forum and became a newbe, I found out I had a c1, solidaxle. You can always pick out a newbe when they reference their car as; 67 c2 or 58 c1. The two terms I learned on here, that I hate the most are "vert", and "dizzy", I'll never say them. Chip

It is really all about internet traffic volume. The number of all remaining 53 - 67 owners combined still fall short of any of the other generations. In order to justify the advertising cost to vendors, they use the number of forum visitors per day.

Never forget, this forum does not exist for the sole purpose of entertaining us all... it is here to make somebody lots of money.

I know about 5 different exhaust manifolds used on the 55 Corvette V8 if you want to nitpick on a couple of unique parts. Most my 55 suspension, brake, cooling, electrical and engine parts will work on my 59. If you are really worried about the correct part, the vin# is what you need to be posting.

Anyway you look at it the "C" type generational names don't make any sense, and contradict any sets of similarities you can name.

I'd like to meet the fool who started all that crap! .....

not to hijack the thread or anything, but, 'vert' and 'dizzy' are terms that can drive me up the wall too.

I try to include the year car I'm working on in every post for help, and, generally ask the year in posts requesting help where the year is vague or not provided. Moreover, where 63s are concerned, I include the month (e.g. "a May 63 car") in most cases because the rolling production changes were rampant...

The C1/C2 stuff is here to stay as is the "vert", "dizzy" and "tranny" shortcuts - so this thread can continue, or die off, to be brought up again in six months (as it always is)...

"Vert" I never heard until this forum, and while I don't like it I find myself using it anyway, like picking up a bad habit. Maybe if "convertible" did not take so much typing.... "Dizzy" grates on my nerves.

"Tranny" OTOH has been around forever - at least since the 1960's. Sounds normal to me since it's so ingrained.

I'm sure this post will not be received well, but c'est la vie.
