Would someone out there measure the length of a stock engine oil dipstick for a '63 389 please? One of my sons left my dipstick on the fender after checking the oil and its gone. I have looked online for a replacement but most say "except 389" or 64 and up. I tried a 20.5 inch long one and dont see anything on the stick. Any help here would be greatly appreciated!

This Is my daily driver Sylvester. He is a 63 CATalina,all stock with the exception of a few period add ons.He takes me to work and home every day but really enjoys stretching his legs on the interstate making the 1000 mile round trip to Daytona Speedway twice a year and cruising through the Blue Ridge Mountains on weekends.
