Assuming you have a stock width A-body 8 3/4, with a 4” backspace in the rear there’s really no point in doing the 1/2” spring offset. Your tires won’t be close enough to the springs to be an issue.
They will be sticking outside of the quarter panel, that combination with that backspace will not fit a Dart with stock quarters. But with the quarters cut that might not be an issue?
