Thank you VX KAT and Riff Raff.

Kat, I've seen those threads, but I appreciate your putting them together for me (and others who may end up tomorrow where I am today). And Riff, WOW, wouldn't that be great if that's all it were? Funny thing is, back in the early 90's, I had a Supra Turbo whose pully went (harmonic balancer - is there such a thing?) and caused quite a racket! Forgot all about that 'til your post. Funny... I'll let you know, but I'm not optimistic.

Best,
