I've installed one. They are pretty. Steering radius is reduced. The manual rack is high effort. Very little weight saving. The geometry for bump steer takes a BIG spacer to get it correct. This was an eyeball guess at proper tie rod location. But its close. My car is also a B body. But with stock steering. Even with header to tire contact mine turns with a way tighter radius. I've driven an A body with this conversion as well. It's also stiff with a large turning radius.
