90 SHO, currently has non VAPS rack and pinion. Can the VAPS rack and pinion unit from a 94 be swapped into this car. Would capping off the VAPS tapped hole be the way to do it? The 94 rack and pinion is quite a bit cheaper and there is no core charge, which is handy when you have to ship across a border. Looking for advice, and thanks in advance.
