I recommend the Toyota box. I have installed them on TF trucks and F100's. It has the same number of turns lock to lock as the stock box so it doesn't oversteer. It also gives you a good feel of the road, works smooth, and trouble free. You will need to reduce the pump pressure on a GM PS pump for it to work properly.
