Re: GMC suspension questions

There is about 1/2" difference in the spacing of the spring pads between the '64 and the '84. If your spring bushings are loose enough, you might be able to move them enough to be able to bolt the '84 rear differential up. The correct way would be to cut the spring pads off, move them and weld them on. The shock mounts will be different as well. As for the springs themselves, they are not interchangeable. You could use the '84 springs though if you transfered the hangers also.

Thanks in advance.
