I am relocating the leaf springs on my 68 charger directly under the frame and have a question about locating the rear shackle.

I called the vendor and they stated that most folks simply weld the top tube (that the bolt goes through) of the shackle to the bottom of the frame rail rather than drill a hole in the frame. To me this looks like it would likely raise the car several inches, while I want to keep the stock ride height.

Has anyone relocated their leaf springs in this manner and if so how did it turn out?

Thanks,
Steve
