I have a 67 Barracuda that has the six cylinder drivetrain and small 4" bolt pattern. I want to know if Wilwoods set for this year has the same bolt pattern, I want 4.5" bp. Do I need to change the whole front suspension just to get 4.5" bp or can I just buy a set of wilwood brakes and rebuild the stock suspension. I am going to install a 440 w/auto. mounted by a motor plate so motor mounts are not an issue. Car will see limited street (2000miles a year max), but will be a bracket car mostly.
