Just curious how many people have used CPP's 400 series power steering box. I have one installed in my 67 and have had nothing but problems. The steering is stiff and there are sticking points in the wheel. When driving and taking a corner the wheel will not return to center on its own. The stock power assist was better than the steering I get with this box. I have a rebuilt front end with all new steering linkage and a CPP mini sub frame. These problems are all still there after an alignment. I have troubleshot this with CPP many of times and nothing seems to work. I think it is a bad box but they insist it is very unlikely. Any comments or feedback would be helpful.
