CV Axle Identification

Hello TW. I am not very knowledgeable on this topic.
I recently removed this destroyed CV axle from my 2011 Tacoma 4wd. I had purchased a remanufactured Cv from a dealership and have now realized that the axles are different lengths.
There is a 2.5-inch lift on the truck that was done by the previous owner. I am not aware if old the CV axle is aftermarket, but I do need to find the same length one so the driver and passenger side match. I am replacing the passenger side. If anyone is aware of how to identify the old axle that would be super helpful.

I have added two photos below to show the difference in length and the axle I purchased from a dealership.







Vehicle Information
2011 Tacoma Access Cab 4wd (trim Level unknown)
Icon 2.5" lift, with tubular control arms, and an Add -a-leaf on the back.

 

The old axle is stretched look at the inner boot.

 

Compress the old axle, they should be the same length.

 

Thanks Yall!. I'll toss the new one in.

Another silly question. A ton of oil came out when I removed the axle. Does anyone know what kind of oil that is?

 

Huge appreciation for this forum. Thanks yall.
