Does anyone know the measurement differences between a 1946 cowl center section (#0452125) and 1947/48 (#452187) ? Are there any visible difference in the parts?

Think its the hinge length and the 46 has a drop in the front of the cowl where the 47,48 is straight. Pretty sure there the same length? Not sure if there able to cross fit?
