Just finished putting down the sound deadner in the 56 buick wagon and my step son cane up so we put the ratty front seat back in because i was tire of sliding around on that milk crate like on gas monkey garage.lol And had him follow me on a test drive.She did a lot better not wandering as bad. But i do have to find some one who has the front stablizer bushing kit, since flea bay only carries them for the super and road master.A lot of things are a 1 year thing only on that on 56 buick specials.Slowly getting there.Bruce.
You may have to go to Jeg's or Summit and buy after market urethane bushings and links. I did and it made a big difference on my '57! KK
Measure the sway bar (use an open end wrench if you have to) and buy them according to size, from Summit, Jeg's or Ebay.
