does anyone know if a crank from a 2003 300m 3.5 will work in a 2006 300 3.5 i have heard that internally all aluminum block 3.5's are the same..thank for your help

 

same if built after feb 3 of 2003

 

thanks.... is there any way to tell the differance by looking at them...the crank in question is from a 2003 300m but the center counter weight is not the same as it is on my 2006 crank... everything else looks the same. i have tried to order a crank from advance auto and autozone but a 2006 is not available when i go back in years the first year available is the 2003... thanks again for your help
