That's a good thing I feel (nothing in filter) "it" stayed in the pump.

I'll be curious what Scott says.

I had sent Scott the pictures late yesterday and he spent time looking & thinking before calling it a day. Neither of us can think where in the world that "spacer" came from, nor can we identify a source for the other little pieces of wire & rod. In the history, I brought the engine home without intake, distributor and pan but wrapped in plastic. Once home I installed the pan, but the engine did sit without the intake for some amount of time with the ports & distributor hole taped. Once installed in the painted chassis the distributor went in, the intake went on, and neither have been off again for 9600 miles. Nothing is safety wired on/in the engine, and no safety wire was done anywhere near the engine that I recall. Whatever got inside has been there since mid-2010, best I can tell.
Scott thinks that something got past the pickup bypass and bound up the pump causing a sudden stoppage that likely bent the shaft on the inner rotating element slightly. That would explain why it binds against the cover. The sudden stop also put the spiral in the shaft until it failed, but the shear pin survived without any deflection. Based on the fact that there is no metal in the filter, and no metallic residue in the pan we both think that the bearings are very likely OK, so the plan is to get a new pump, new shaft, some gaskets and after a good cleaning button it together, say a prayer and fire it up with an ear tuned.
Just to satisfy my curiosity I'm going to try to get a dial indicator on the oil pump elements and see if they are indeed "tweaked". There should be only .002 to .003" clearance between the elements and the cover, so any deflection is too much. We'll see, wish me luck!!
