If you can't find a small or big block Mopar in a local junkyard, and you don't have a local fastener place, you'll be looking at McMaster-Carr or another online fastener place.

The crankshaft vibration dampener bolt is 3/4"-16 UNF, 2.3 inches long, with a 1.5 inches minimum length threaded area.

You will also need a thick washer, the washer is 1-15/16" x 1/4".

Motor isn't together but it threaded into the crank no problem.
