I have the SCP spindles on my 69 Camaro racer.
The 8.5" tall SCP (Stock Car Products) spindle is about an inch taller than a Camaro spindle.
Spindle location is close to a Camaro location.
The steering arms for rear steer are available but they are very long and turn inward a bunch. not good for steering ratio or geometry.
Balljoints required are bigger late 60's chevy truck type. You must change to them or maybe use a tapered shim to space the hole in the spindle down.
Stock Camaro is 7 degree taper, but smaller size.
The extenders make the front end stiffer in roll, similar to a slightly larger antiroll bar. So it would tend to make the car understeer, but the mod gains tractiion too, and that reduces understeer.
