My 55 ford mainline  suspension is all in good order but the car sits dead level.I would like to raise the rear end 1-2 inches.I have new stock rear springs,overload springs on the shocks and I machined up a couple of little 3/4" spacers that go between the bottom of the rear shocks and the mount.Anybody have any ideas? I don't want to lower the front end,just raise the rear a little.Thanks.
