Photo request. 1966 dart manual transmission stuff
You already have the pedals , flywheel ,z bar , so get a 65 A833 (the one with a flange on the back to tale the ball & trunion ) The shifter and the hump can come from a 63-65 same for the hump use a 65 iron 4 speed 6 cyl bell and a 10 inch clutch will bolt right on to your existing flywheel with that small 9 1/8th clutch that is there now .There is no new stuff for these and in 66 the 4 speed wasn't offered as an option (in the US anyway) for a 6 cylinder car so again 65 and down to 63 .You can use the later stuff from the 70's with the overdrive 4 speed but that is more complicated and expensive . For a driver the 65 set up is really nice and cheaper to do.This trans is not as sought after as the later ones and way less EXPENSIVE
