Do the ride tech Delrin bushings work with stock upper/lower control arms for 67-72 as the steel bushings thread in. Are these designed to work with 73 and up control arms? Looking at the pictures the Delrin bushing sleeves look smooth versus being threaded. I made the mistake of torquing my upper/lower control arms to spec with the frame lifted versus loaded and experienced binding when attempting to put my upper bump stops in. I now have to loosen the control arm shaft bushing caps, lower and then torque. I also don’t have any weight on it, it’s just a roller at this point. When I use my body weight 200 lbs. the front end doesn’t compress much, it’s pretty stiff. I think this is due to torquing my control arm shafts with the front end off the ground.
