Another mod that will make the biggest impact to that mustang is a set of roller perches from here,
Vintage Mustang Suspension and Steering Friction Free Roller Bearing Performance - Opentracker Racing Products
Or diy from,
DazeCars, Ford Galaxie Mustang tech and restoration
So the shelby drop with negative wedge and the roller perches will totally wake up that cars handling.
