Hayward Sand Filter Valve

I have a Hayward E series sand filter. I need a replacement Key valve that directs the water due to my daughter breaking the shaft on the old one. The valve has the numbers SP 0714 C stamped on the bottom. Many of the replacements have different codes like sp0714T and i want to make sure I get the correct part. My top cover has Vari-FloXL and is a circle with the raised bolt slots inside the circle. Can’t read the model number and info on the cover due to age. The inside of the actual cover has SP 0714 B with a 2 under that stamped on the under side. Thanks for any help anyone could provide!

The replacement key, cover, and handle assembly is part number 4703-20.
