Re-installing damper on 383.

HemiSSDart said
I do it the old school way, tap it on with a piece of wood and ballpeen hammer, then use the bolt and an impact to seat it. I always use a piece of wood that only contacts the inner portion of the dampner so that the rubber ring doesn't get moved. Been doing it for 40 years with no issues.

On big blocks I use a small block bolt to pull it on until I can get multiple threads started on the short big block bolt. Small blocks get knocked on a bit with a rubber mallet.
