Crankshaft Pulley Bolt missing

Hi guys!

Started up my Duster earlier to find a very bad knocking noise coming from the pulley area, I got underneath the car to see one of the bolts is missing and one of the others was super loose!!!! I've tightened them up and the knocking stopped however it looks like the pulley has moved around as the alignment isn't right?

I bought the car from California the other year and had it shipped over across the pond to the UK where me and my dad have restored the body work.

I don't have a build sheet unfortunately but from what I was told it's pretty much a stock 360 with a cam from an RV in it.

This is my first Mopar so I'm still learning the ropes, but I assume I will be able to loosen up the other bolts and spin the pulley back into place? Then put the missing bolt back in it's hole?

I did find a bolt that looks very similar to the others in the pulley on the floor but thought it came of my dad's Lincoln...turns out it has probably dropped off mine!

I have been chasing a squealing noise everytime I put foot to floor, could this be it? WhatsApp Image 2022-04-29 at 6.17.23 PM.jpeg
