In the interest of tying up loose ends, I believe I've eliminated the squeel/screach. I finally got a guy I know, who's "into LBC's", to come over and listen w/a talented ear. He thought he heard 3 sounds and located one where the external oil tube was vibrating against the exhaust down pipe. At the end of the evening we couldn't locate the other sounds origination points, but he was very sure the noises were coming from somewhere outside the engine. This was the information I really needed to know. With Clay's assurances I began concentrating on surface to surface vibrations. The other day I realized the steering column cowling was vibrating against the column. When I removed the lower half of the cowling the loudest noise when away. I believe the vibration was traveling down the steering shaft and was resonating in the steering box. This left me w/an intermittent noise that sounded like it's coming from the back of the engine, maybe from the clutch housing. I took the car out for test drive around the neighborhood, today, and after driving it around for a bit, under heavier load than I've previously driven it, the final noise went away. I'm beginning to believe the final noise may be the throw-out bearing, because now that I'm able to get a good 1000rpm idle, engaging the clutch does cause a significant drop in rpm and will sometime die. So it looks like a clutch replacement is in order. It's something I should probably do, anyway.
Thanks for the help and suggestions, With luck, I may be able to get this beast on the road by spring...here's hoping.
