Hey Don, while any "looseness in the King pin bushings is undersiable, it may not be the only the cause of the shimmy, How are the front tires? Air pressure even? Try swapping front to back? Axle straight? How tight is the steering box set up? What about the backing plates? are they tight as well? Have you got at least 25 percent crush on the tie-rod springs? When you really look at all the moving parts in the steering system, getting everything to specs. can be daunting. But when it working right, they are a joy to drive. After all you have done it just might be the King pin bushings, but you'll never know until you change them out for new.
I had some "fun" with my coupe, and fixed the shake buy reducing the toe-in by a eights or so. After installing five new tires, she was fighting me so the toe-in was readjusted. Drives nice now.
Good luck!
