Both have the same casting Number. 2806178 but I was just going by the stamping date. the 67 is 5-67 the 68 is 12-17-68. I will have to go to shop tomorrow as the 68 has some kind of weird carb and plate on it. I will pop it off . The 67 seems to have small intake holes in it.
After almost 71 years I am on my last car. A 65 Plymouth Satellite straight axle altered wheel base car.
