I thought that I would post a shot of the Hellwig leaf helpers that I use. I have used Hellwigs on a number of my Mopars over the years with good results. You can raise the rear several inches with them. And you can adjust the height side to side and adjust the weight balance if you want, too. I mount them over the spring rather than under so that they really can't be seen. It takes a minor modification to the rear U bracket, but it is minor. I have ran a best of 1.5 with these on this car, a '70 Cuda, and they have been on there now for about 6 years. Seem to be quality pieces. Just an FYI.
