Found my dads original 1971 duster!

Hey guys. Question. I bought an aftermarket 727 transmission dipstick. It’s very hard to read. It’s like a bluish/anodized, shiny colour. Very poor design. Im also not convinced or confident that the scale markings are accurate. Anybody near me have one that I could buy, borrow or look at? My level appears to be a bit high, but don’t want to take any out until I know for sure. Thanks!
