When I bought my coupe a few months back it included some extra half shafts, some with end flanges still attached. I took them apart and found that a couple of them had a different profile than the other ones. I would appreciate if anyone has an idea if maybe one style was 63 only or if maybe some aftermarket company made some different. They are both the same size and bolt pattern.
Thanks Roy. I couldn't find any documentation that 63 was different from the others. It says nothing in the NCRS judging book about being different. Is there anything that shows it or do you just know from experience? I am trying to keep this as authentic as possible. So far I have 95% original or NOS to replace what is needed.
I picked up a lot of extra stuff that was in storage when I bought the car.
I'm not sure if all 63's had this or exactly when the transition is (early 63's only per comments on the linked thread), when was your car made? If you want to sell the one on the right let me know, I have 1 good one and 1 cracked one (not on the car) - I keep looking for a second good one.
My car is one of the last few hundred made (made in the second week of August 63. I show that being the last week of production) so they must have used them thru the 63 production run. I am going to put these back on this car but will keep an eye open in the rest of the parts I accumulated when I got it.

I have restored several 63s and dismantled several more. All the 63s that I felt were original had this flange. Roy
All the original 63's I have worked on, used those flanges. The later ones worked better and those are just a few of the things that changed as the years went by.
All of the can be bent, look for flats under the welds where the shaft was crushed in a vise. The flange should be flat, no rocking in them. If you go with better u-joints like solid Spicer, you won't get them installed if the flange is bent.
63 outer axles to mid production were slip fit and failed in use, all vette outer axles to 1982 were then an interference fit.
63-64 differentials also had plenty of issues.
Point being, look at your car close. If it has not been serviced in decades, you may find a lot of these and more on your car.
It was sitting in a garage on jack stands untouched since 1978...I got it in June and it was the first time it had seen daylight in 45 years. Nearly every part on it was good and original or he had a NOS part to replace it.
I am taking a guess that the one on the left is a 63 only spindle flange wheel side??? Anyone that knew the answer to the other flange knows this I'm sure.
The one on the right has been used from 64-79 and is the better one. Look at the face of the one on the left, beat up and often used as is. All used flanges look like this when you take them apart. I parallel grind the flanges.
post #6 shows the early 63 flange. Your call on what you use. I have been a member of NCRS for over 30 years, but I build to application as I prefer stronger parts in my work.
I'm trying to keep it as original as possible. I won't drive it except occasionally. I am still contemplating whether or not to keep the j65 metallic brakes on it or go to organic shoes. I am told the metallic stink unless you heat them up.

I disagree on the J65 brakes, no appreciable difference cold between standard brakes and J65, and I have both.
I did know know about the unique 63 flanges. That's the second thing I learned about 63s this week....
