PST 1.125" sway bay wont fit.

My suggestion is if the bar is otherwise clearing the K-frame, use the forward bolt location of the bracket off the K-frame to mount the bushing clamp forward end (longer bolt of course, (use grade 8s)), drill a new hole for the rear of the bushing clamp to bolt on to. Use wide thick washers at the bolts in order to better support the bushing clamps. Also, wrap a layer of Teflon tape around the bar where the bushing supports it. It will help retard squeaks and slow down the urethane bushing wear where it works with the sway bar. Another point is to simply keep in mind that you are working with a P-S-T product undoubtedly made by addco and minor adjustment must be made. If you want no hassle installs, then you must use factory or something along the lines of hotchkis type parts. My 2 cents worth.
