Pulled CV axle to replace boots, new boots don’t fit…what axle do I have?

Hey guys, wondering if anyone can help me out here. I pulled the CV axle on my 2011 Tundra to replace the boots. Ordered boot kit only to find they do not match my axle which must’ve been swapped from original.

Anyone know what axle I have or a way to find out? I would rather just order boots and clamps and throw her back in but having trouble finding the right boots. Also, if this is an axle from another Toyota, say a four runner or something, is it safe to run in my tundra or should I just buy a new axle?

I’ll post pics.

 

Aftermarket junk, they sell new for $50 - $150 depending on what it is. Not worth rebooting.
