Jerry at MGS fixed me up. I now have a "complete" parts set with all the springs!
He said he didn't really know what spring was what, and that I should fax him a pic of the spring I needed. Thanks to Ilya's photos, I was able to print and fax the pics. They showed up as promised! Before they showed up, I was looking at the discarded section of an AK FCG spring as a donor for the top cover hinge spring. While I'm sure that would have worked, I'm glad I didn't have to go there!
Jerry at MGS also said he still had a "bag of springs" so anyone missing some PK parts should figure out what they need and contact Jerry. Between the photos that Ilya has an my pics, you should be able to figure out the small parts.
I'm a very Happy Camper today!
