Default Are axles different for posi and non-posi?

I helped install a non-posi rear in my friends 60 the other day because he had a 4:56 posi in there.
He just called me and he claims the axles will not go in and they slip right into the posi-rear.
Are there different axles/spline for non-posi?
Thanks,
Joe

So, Joe, the only reason the axles won't go in seems to be he can't get the splines to mesh?

Can’t remember but either the posi axles are longer or the non posi. I have some spacers that go on c1 axels but can’t remember which ones are longer . Sorry

DZAuto, Tom, has explained this at least a few times. I don't remember what he said. A Google search of axle lengths corvette forum c1 should find the answer.

Found this in another thread. Compliments of Tom (DZAUTO):

The 57 Vettes/pass cars use a thinner bearing (RW307 series bearing) than what is used on 58 pass/58-62 Vettes (RW607 series bearing).

The 1957 year model WAS THE ONLY, ONLY, ONLY time when there were separate posi and non-posi axles. In 1957, again, ONLY, when either a Corvette or pass car received positraction on the assembly line, did that car receive positraction axles. The axles for posi were 1/8 in shorter than non-posi axles.

The question frequently comes up, why did 57 only get shorter axles and NOT 58-later cars? The answer is TOOOOOOOOOOOOO SIMPLE, because in 1958 and later Vettes/cars used the thicker RW607 series bearing, which was 1/8in thicker-----------------thus, no need any longer for 2 separate axles.

ALLLLLLLLLLLLLLLLLLLLLLLLL 55-64 pass car axles and ALLLLLLLLLLLLLLLLLL 56-62 Corvette axles have 17 splines. Thus, all the above mentioned axles will fit into ALLLLLLLLLLLLLLLLLLLL 55-64 (pass car or Vette) axle gears in the differential.

I'll bet I'm not the only one here who would like to enlist in a DZAUTO boot camp, where us grunts would sit on bleachers as Tom bellowed at us from behind a podium, stating arcane facts and figures through a bullhorn. Failure to retain bits and pieces of vital information would result in push ups and laps being run around the compound......

Would someone else with better grammatical skills please respond to the original question and provide a better solution and answer to the question so that he can get the axles installed?
I apologize for trying to emphasize details which intuitively seemed to be important.

It seems that some individuals criticize and belittle anything and everything which is posted by others, no matter what the subject matter may be. I do not understand it!

In my constant search for knowledge, I read all your posts and you seldom misspeak. You just make it tough to read (and confusing) for no reason. Wading through all those exclamation points and the stuck shift key is like a cross eyed batter up trying to hit the baseball.

Keep the posts coming Tom, as it is greatly appreciated by all. The bold print and emphasis with shift key just lets me know what follows is important. The depth of your knowledge is awesome.

Why not just use the bold button instead of all the exclamation marks and locking the shift key. Much easier on the old eyes.

Good grief....

Tom is always the definitive answer on this stuff and keeps it in his memory banks no less...
Something my aged brain finds a chore...

I still have to look up his posts to remember how many teeth are on a C1 flywheel ring

Now - if some would just forget the putt-putt-PUTT stuff I would be grateful..

We all have a different way of emphasizing things in our posts. When I want to emphasize a written word I capitalized it, some consider it shouting on the net but that is the way I speak buy raising my voice on a given word. I also quote a post I am responding to so people know who I am speaking to and bold the portion of their post I am responding to and then bold my comments. We all have our idiosyncrasies.

I have met Tom in person and he is a great guy and always willing to share his knowledge so give him a break as to how he gets his point across.

My only interest is to get responses presented in some kind of intelligent manner where they are readable. I don't need to see ALLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL and !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! to know what is important in a sentence. Maybe some of you do?

I went to school in Indiana. Maybe they teach differently in Oklahoma? Or wherever you like to see ALLLLLLLLLLLLLLLLLLL and !!!!!!!!!!!!!!!!!!!!!!!!!?

I was casually catching up on forum posts and having a Stella when I read Tom's above reply with a mouth full of beer. I have no idea why but it was so funny to me to read the end in bold print,,,ALLLLLLLLLLLLLLLLLLLLLLLLLLL all my beer came out!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!. Tom, I read everything you respond to and I personally don't care how you relay it. Its your trademark to me. Bill
