What crank is in your car now? Cast or forged? What converter did you order?
Sorry did not mention that specifically...
The weighted converter implies that it is a cast crank 440 but a lot can happen over 47 years...
It is still a cast crank with large damper and the original converter had the weights.
Before the replacement the vibration was not present.
The replacement was a reman from a local gear and drivetrain shop. "Precision" brand, which they sell a ton of.
It is the correct one for the application based on the part number and also visual comparison of old and new.
