Chrysler starting using cast cranks in the 340 just three months before 72 production ended. This is a very misunderstood fact......
Also if you know your Thermoquad history, 72 was the best performing unit out of all years......
Personally I love the 72 tail lights over the 70,71......but this one year only production makes it tough finding replacements..:(
