f.i. l.t.h. for right hand driver?

BGTV8

I have Stillen Stainless headers on my car, and at about 15 degrees of left hand lock, the nut on the steering column joint at the rack "just" touches and I get the faintest vibration which was a little off-putting until I figured out what it was ... I will eventually replace the bolt with a grade 8 half-height boolt head or perhaps a cap-screw to avoid it ....
