I have no 55 cranks to compare or measure. I'm guessing differences have to to do with piston skirt to crank counter weight clearance

According to my cataloug page nov 1 1955 only 3 cranks.
440594. 5540 (i assume the 320 engine)
440913. 5560-80 (i assume 352 engine)
476009. All 56. (352 and 374).

Is there any dimensional difference (width or radius etc) between the counter weights of the 3 cranks that mite be due to piston skirt clearance OR Clearance at flat front and rear sides of piston near the gudgeon.
