Crank accessory pulley wobble

[Whitfield]

What's the part number?

Anyone Google it yet?

Search for the part number on Ebay?

Oh, here's the part number, 14067703

Can someone tell me where I got that part number?

My concern is can the wobble be considered failure? Trauma? Wear?

If so what is the method of failure? What causes the change?

I know most 80's and earlier V-8 chevy crank pulleys do not run true like today's cars but at what point do we call the 6.2L pulley bad?
