How to Identify OEM vs Aftermarket CV Axles

Getting ready to do the CV boots on our 2005 4Runner and need help figuring out if it has aftermarket axles or not.
I was told the 5th Gen CV boot kits are interchangeable with the 4th gen.
My 16' 5th gen has 11-1/2" diameter (OD) inner axle cup and the 4th gen is 10-1/2" diameter (OD) and the 4th generation does not the cutouts to use a chisel on to remove them.
Do these look OEM?

 

This is one of the OEM axles from my 2003 when I was installing new inner boots.



Both sides have the cutouts for using a prybar on the axle for removal. I don't know if that changed with later model years or not tho.

These are the inner boots I used - https://www.offroadsolutions.com/products/high-angle-inner-cv-boot/

 

You should also reference this thread, which covers OEM CV axle differences -

 

I have a 2004 CV axle from my limited V8 sitting in my garage, would a picture of that help?

 

I'm sure I have aftermarket. I'm sure your's have the cutouts for removal like xtremewlr.
