The final solution.. : I checked the thrust angle and reset both sides so they were closer to where they should be ( I have installed Watts Links from Mickmate to hold the rear end stiffer than before). I then made certain that both rear wheels on the Vintage Wheels adapters were running true and round within about .010 inches. With all of that done, there is no perceptable shake in the front end under any circumstances. It appears that the problem is solved.
