Rattling noise

I have a 1984 pickup 350.  I have a rattle coming from where my flex
plate/ring gear assembly is.  Almost sounds like a ring gear rubbing
against my inspection cover.  I took my Inspection cover off, that
wasn’t it, but I could get my ear a little closer to where the rattle
is.  I’m hoping it’s not the rear crankshaft bearing.  What kind of
sound would that make, and how far is my crankshaft bearing from my ring
gear?…..thanx

    Is your starter drive disengaging completely?

    Probably a cracked flexplate. Very difficult to see without removal. Good
    luck.
