New CV half-shaft doesn't fit?

[mfsoler]

I have a 2000 Chevy Cavalier 2.2L Manual 5-speed car. The driver side CV axle is worn out and making noises. I ordered one from Autozone (part #9463) and O'Reilly Auto Parts (part #60-1219).

The one from O'Reilly's was about 2 inches shorter than my old one. When trying to install it the shaft was extended all the way out, causing the boot to collapse on itself. My old one didn't do this and the new one shouldn't have either.

The one from Autozone looked completely wrong.

I have tried to find one online that is the right length, about 25 5/16 in., but can only find ones that are 23 inches.

Neither parts store knows why the parts don't fit, My only other option is to take the old one in to get repaired.

Does anyone know why my new CV half-shaft doesn't fit or if my old one can be repaired?
