I was hoping it would work but like you said im not 100%. I thought that since the oil pan was from a 65 dart it would have worked since its between the same years A body.
Is the oil pan from a 65 or a 67 as mentioned in your first post? If the pan is definitely a 65 (or 64 or 66) it will fit the chassis with the original slant 6 centerlink. If the motor (and pan) is from a 67, again, the best solution is find the early A pan AND oil pickup.
