Convertor weights

The Mopar performance manuals show the placement and amount of imbalance
for the various externally balanced engines,yes they are different for each.A correct kit
w/template would make it fall off the log easy.I did it to a cast crank 440 11" unit,but
made my own weights,worked like a champ & the fancy flexplates didn't exist then. I
suppose today for the coin I'd just buy a new flexplate and be done w/it.
