1 of 51 ! can it be possible :

So ! lets start this : 24 817 duster 340 1970 were made:

3018 were shipped for canada : 29.66% of all duster 340s were 4 speed cars ,
so.. 3018 divided by 29.66 % = 895
895 x 5.7 % ( Galen Govier production of fj5 340 dusters ) = 51

51 made fj5 duster 340s sublime green 4 speed for canada , i dont know if you guys have other infos on this but i think that its pretty rare and close to be very accurate
