Wow. Just when you think you've seen everything.
Yes that is a 69 or earlier k-frame. That probably is the factory ebody/70-72 bbody sway bar since the width look to fit the Ebody/70-72 bbody LCA's.
You can buy new reproduction sway bar bushing U-shaped brackets.
Thank you,
I just ordered new sway bar parts from Bill Rolik yesterday since the bushings and U shaped brackets were crushed that's when I started my Goggle search and realized something didn't look correct. I guess I'm looking for a correct 383052 K frame.
