Hi Dave, I posted this a few weeks ago.... While not an expert on anything, I did find some information. Click on the link to learn more. It looks like the Maltese cross indicates a .001" undersized crank. Also I found that there are 2 different casting numbers on the 1959 thru 1965 413 engines. The other number is 2205697 and that number is listed as being for "passenger cars". Not sure what the 2120529 is for, but that is the other number listed for 1959 thru 1965 413 engines. Hope this helped a little. Safe and Happy Holidays!!!!
