I'm wanting to use one of your gasser straight axle kits on my 1965 Mustang Gasser . I measured the frame rails they are 32 inches to the out side edge . The best i can measure the hub to hub is 52 inches . I want to keep the front of the car as low as possible .. Would I have to use a drop axle to do that ? thanks for your help Greg.
