One of Ford's not so good ideas was the addition of an offset shaft on the front pivot of the lower control arm on 1960-1964 Galaxies and Mercury Marauders. The offset shaft actually moved as the car was traveling and encountered road irregularities. The camber, caster and toe would all change dynamically as the car was moving. Ford did this to give the car a nice plush ride, and it worked well at slower speeds.
Once vehicle speed was increased, the cars felt like wet noodles. Ford knew this fact and tied the lower pivots together with a bolt on bar on taxi cabs, police cars and any car that would see extreme road conditions. I have seen a couple of these bars on Galaxies over the years. There were also some straight lower pivot shafts that would not move and change the front end settings, but they are not readily available. I have also read about people welding the shaft in position, but that makes removal of the lower A-arm more difficult later.
I fixed the "wet noodle" feel on my road race '64 Galaxie by bolting on a simple aluminum radius rod and a couple of brackets to the offset shaft on each side of the car and effectively tying them together so the A-arms cannot move.
Here is the offset shaft I am talking about. One side of the shaft that bolts to the frame is offset about 5/8" from the side that bolts to the lower A-arm:
I built a small bracket out of 3/16" plate that will bolt to the offset shaft. The bracket has a 5/8" hole to slide over the offset shaft, and a 5/8" grade 8 bolt welded to it. The bracket also has a slight bend to allow the radius rod to bolt on straight:
The original nut that holds the A-arm to the offset shaft is used to hold the bracket on:
The aluminum radius rod is 19" long and has left and right hand thread male rod ends on each end. This is a common circle track item and can be bought from Speedway Motors:
The radius rod is adjusted for length and is now bolted to the "stud" on each of the brackets bolted to each of the offset shafts. A self locking nut is used to secure the rod:
The radius rod now will effectively tie the two offset shafts together so that they cannot move. The feeling of the car at speed is nice and stable with no movement at all:
