so, i have been looking into this for while now and haven't been able to come up with anything as of yet. What is the difference in the hemi flywheels between gen II and genIII.

gen 2 has a part number p4529143
gen 3 has a part number p5153592

both are 8 bolt and have 130 teeth. plus they both take a 10.5 clutch, if i'm not mistaking. oh and 30lb.
