In a 74 Duster the standard 3 speed manual was the A-230......which is easy to identify due to the inspection cover on the side as compared to the A-250 that is a toploader.
I couldnt even give my 60k mile slant away.....then out of the blue someone offered me 200 bucks for it, no transmission or assessories on it. Just gota wait for the right person who thinks they need it.
