1997 Challenger 1800 Impellers with pictures. Are these stock?

[daboostcreep]

I took these pictures today of the impellers on my 1997 Challenger 1800. I don't have anything to compare them to as known stock, and I couldn't see any markings. Are these stock impellers?

Those are skat-trak swirl impellers.

You will need to remove them to see the markings at the base of the hub.
