Difference in axles?

I bought some axles the otherday and tried to put them on, but my stock bolts wouldnt fit through the hole. Whats the difference between years and such. Also whats different about them.
Thanks

ABS and non-ABS is the main difference. You will have a hell of a time getting it into the diff if they get mixed up.

That and if you have an ABS car and a non-ABS axle, you'll tear the axle apart in about the first 1/8 mile.
