I had a bad wheel hop prob with my 69 when I first got it. Of course the rear of the car was about three miles in the air and the "lakewood" style bars pretty much fixed it. Now it's so low I can barely get a jack under it. When tightened all the way down they have a tendency to clamp the spring and reduce travel (which lowered the rear). I was told to take them off for that reason. I haven't driven the car yet to see what kind of difference there is yet. They did hang so low as to make driveway and speed bump driving a real drag(literally).
