My swaybar contacts the K frame in two places, don't know if this is designed in or it needs to be spaced away to stop the contact. My set up: '74 Duster and K frame, factory disk brake / sway bar car. I have replaced the stock 318 sway bar with a Helwig 1.125" hollow swaybar with the provided poly mounts and endlinks. Using the stock swaybar bracket/bars to mount the poly mounts to the K.
There are two areas inside the K that hit the bar at the same location on both sides. They feel like they could have been stamped into the upper half of the K when the metal was formed and therefore are a designed support, or, the larger diameter of the bar just exceeded the designed in clearances and now it's hitting.
I can see reasons for both to be true. Don't remember any mention to check this in the instruction sheet. Any ideas?
