here it is,
the 1st bo29's had steering problems. When going thru the traps at
'high-speeds', the cars would over-steer.
As per jack werst {'mr. 5 & 50'}
"front-end trajectory"
the cars did not come through without problems. The front-end geometry
was not 'square' as we say. And there were problems with the handling/suspension.
With the 'shim-plates' installed between the k-frame and body-frame, the
body was now higher. This put more pressure on the lower-control arm,
and there was an alignment problem with the 'straight-plane' of the steering
control-arm.
There was also increased pressure on the ball-joint due to the odd-angle,
and on 'some' cars the pressure even forced the ball-joint to fall out.
In the 1st-week of april 1968, we tested the bo29 at englishtown, new jersey.
Man that barracuda was all over the place once we hit 120 mph.
Once the weight came off the front-end, the barracuda would over-steer.
Chrysler shipped us new 'control-arms', and these units had an angled-arm so
the front-end geometry was square.
They also shipped out 'new' front-spindle assemblies with the proper angle.
After those units were replaced, the steering was close to 'tight-as-nuts'.
