383 Oil Dipstick

I am looking for a 383 oil dipstick for my 68 Formula S. Engine has the 893 oil pan. I don't know if they are different length from other 383's so here are the dimensions of what I am looking for, courtesy of member MOPARMITCH:

Length from tip of dipstick to the insert stop lip on the handle = 20 inches
Full line is 2 1/8" up from tip, add line is 1.5" up from tip.

Numbers matching car so would really like to find a correct dipstick. Can't seem to find a CORRECT new one listed anywhere. Used is fine.

PM me if you can help. Thanks!
