Miniscule movement front ward. IIRC I think it was 3 or 4" inches up front and 4" inches out back. A little fender trimming had to be had on the couple of them. But it was covert for its time. No one really noticed.
Dick Landy did his own 1964 modifications and was supposedly first in line, but that is left to argument. Since it was Jim Thorton and Hoover that were closest to the Ramchargers, I can argue that their car was probably the first.
