The heavy washers supplied with the bolts can't be used as it makes the bolt too short to fully engage the nut. Holding the arm in place as a repair item wasn't the sole purpose but they can be used for that with some attention to detail and a bit of care in how you do it. There actual intended purpose is to create a grease path so the greasable bolts can be used without the grease leaking out into the slots. They work perfectly with sound Lower Control Arm mounts and only need a bit of fiddling is that isn't the case. If the mount is very worn, the solution may be to clean the outside of the bracket and fully weld around the washer so it becomes part of the bracket and will hold the bolt in place with no issues. The washer should be put in the slot and checked to make sure the shoulder does not stick inside and if it does, weld the washers or file the shoulder down slightly so it is slightly lower than the inside of the bracket. If the previous control arms have even been run when they were loose, it is likely that the inside of the mount is worn down and now the shoulder on the washer is what the end of the ball clamps against and that is wrong. That way the shoulder on the end of the JJ ball is clamped in place on the bracket and when the clamping force tightens everything, the joint won't move and the slot is sealed to keep the grease going where it needs to go instead of leaking out the slot. In order for them to work correctly, the machined shoulder that fits into the slot has to be slightly thinner than the OEM bracket.
