listers, I just put my rear suspension together on my 74 however there is a slight knocking on both sides when the rear of the car moves up and down. I can lift the rear of the car up and down and I can see the centering cone at the top mount moving up and down. First, everything is new back there - the pillars with new wheel bearings, new KYB excel shocks, new top mounts and new control arms. I originally put Vick performance springs on and noticed the knock so I replaced those with original springs but the knock is still there. I also put the Bigfoot strut plates on but my shock towers didn't need them and I'm tempted to take those off to see if that makes a difference. Also as per Matts specs, I used the spring perches for 80 - 88 cars when installing the KYB shocks on an earlier car. I'm sure the top nut and cone is put on correctly and I couldn't tighten the nut any tighter. I had Koni struts on the car prior to the rebuild and had no issues. I've run out of ideas and I hope some of you can lend some advice.
