For info:
Cardone Select part# 55-83333 is the correct pump for the SLK32/SRT-6 and can be found for around $100 from partsgeek.com

2 things to note:

1 - If you are mounting a pulley in the unused hole above the alternator, ensure you drill it out before mounting to the correct size for your bolt PRIOR to mounting... (only applies to people with PSK setups)

2 - the 2 holes at the top, which the black bracket screw onto, may need to be tapped. Mine had non-threaded holes. You will also want to do this prior to mounting.

Other than that, it is a perfect match. It's also brand new and not a reman.
