Thanks Nick. I have an adjustable panhard bar,and the car has the original F41 rear sway set up. I'm wanting a set of Vintage silver 15 x 8 Torque Thrust D wheels with a 4 to 4.5 backspacing,but I dont think they make that backspacing anymore. All I've been able to locate on American racing site is 15 X 8.5 with 3.75 back spacing,,I fear those will rub on the wheelhouse lip. Open to any suggestion though,and thanks to you, Nick, and the others who have provided info to this question. Not sure what I'm gonna do.
