Junkyard 5.9L Magnum + Edelbrock LA heads build

Got my PRW crank damper in the mail today, it comes with 3 removable counterweights but no instructions on which weight for which engine! I had to look in the PRW catalog for weights, found the ones I had, lo and behold two of them are marked with the wrong number (heavier one meant for LA 360s has the P/N for the 5.9 Magnum counterweight). Based on what I know about Magnum engines having lighter rotating assemblies I'm assuming the lighter of the 2 weights should be used with my Magnum short block...

BTW I was going to get the Pro Products damper but when I placed the order on Summit it said it wouldn't ship until mid-February, don't feel like waiting that long lol
