Hurst 5973 or 7063 shifter stick

Im trying to figure out which shifter will work best on my 70 duster 4spd with buckets and manual steering( big steering wheel) i want that nice rallye look. i know at some point both 7036 and 5973 shifter sticks were factory options. Is there a difference between them? Any specs available like length and offset? Im not sure on the shift mechanism but its a 2 hole bolt on. Also is anyome selling one?.
Thanks for your help
