I bought these drive shafts from the bay (link below) and are trying to find out if they are the real mcoy, a tall order from a picture I know but any advice or tricks to tell I would much appreciate it

The seller said they came out of a scrapped 4x4 saph cos and were kept as spare but then the owner sold his cossie and he sold the shafts on his behalf as the owner was a friend, I asked the question to the seller and he couldn't say for definate only the info as above but offered a refund and was sweet about it,
I didn't pay the earth for them as you can see but if they are not cossie shafts and turn out to be xr4x4 ones I'll aim to sell them on
Help much appreciated
