CVF Racing water pump?

backing plate on the GMB SURE DON'T LOK AS GOOD AS THE OND KROOSER POSTEB looks riveted wtf?
I’m running the exact same pump that they sent but it in Gates branded. Exact. The plate is spot welded to the impeller vanes but the diameter is obviously much smaller within the cavity than The version Krooser posted pics of. The impeller is obviously a much larger diameter, filling the cavity of the pump body. I have a hunch it’s what you get from them now. Will see......
